OrCAD Capture 17.4
Simplified Project Creation and Simulation Flow: The 17.4-2019 release introduces the concept of universal projects, which allows you to create a project without having to select a project type. Further, with the new user interface, you can create a project along with the option to enable PSpice simulation.
Streamlined Workspace: OrCAD Capture provides you with a large set of user-friendly tools and features to easily capture your schematic design. With the 17.4-2019 release, the workspace has been enhanced to ensure fast schematic design creation in an optimized manner.
Many new improvements have been done in the Capture workspace to ensure greater ease of use and a satisfactory user experience.
Application and Canvas (Schematic Page) Theme: In the 17.4-2019 release, Capture opens in a dark theme by default. A dark theme reduces power usage, improves visibility, and makes it easier for screens to be read.
Well-Organized Toolbars: Toolbars have been reorganized according to function, and the icons in these toolbars are arranged based on their menus. You can toggle individual icons on or off in the toolbar.
Workspace Customization: Panes are now displayed consistently across all OrCAD applications. All resources opened from a project are displayed as horizontal Tabbed Documents in the canvas area. By default, all panes displaying any kind of output are at the bottom of the application. If multiple panes are open in the output window, they are displayed as docked and tabbed panes.
Enhanced Search Pane: The Find command is now available as a separate pane, called the Find pane. It allows you to specify a property value string and lets you select the object that you want to find. Capture then searches for all objects that match the specified string.
Online DRC: The enhanced user interface of Design Rules Check introduces a new option—Online DRC. Set this to On if you want to check and list design rule violations dynamically as you create or update a schematic design. The Design Rules Check window enables you to set the rules to be run in Batch and/or Online mode.
Design Sync: To efficiently and easily synchronize changes from schematic to layout, and from layout to schematic, a new user interface, Design Sync, has been introduced in 17.4-2019.Using the Design Sync window, you can view the differences between a schematic and the layout for a board, and synchronize the layout from schematic or schematic from layout. Designed with the capability for in-memory synchronization, you can use Design Sync to review the type of change, addition, modification, or removal of a design object without saving the design/layout.
Accessing External Parts from Capture: Using the Place – Search Providers menu, you can search for and download millions of electronic components, symbols, footprints, manufacturer datasheets, and 3D STEP models from Cadence-supported content providers — SamacSys and Ultra Librarian (link is external). You can easily find the part you require and place it in your design. The part, its associated metadata, and any available ECAD models, are saved to your local library.
PCB Editor 17.4 QIR 2
Viewer Integration. Launch PCB Editor viewer from the project hierarchy.
3D Canvas enhancements. 3D mapper now a part of 3D canvas, replacing Allegro (2D) menu. Simplified use model and GUI enhancements. Improved accuracy of collision detection and distance measurements. Additional support for mapping native CAD models (Parasolid, Siemens NX, CREO, SOLIDWORKS).
IPC2581 enhancements. Additional support for rigid flex (bend detail and stack-up profiles), Countersink/counterbore, square drill features, net shorts, and impedance specifications and nets.
IDX enhancements. Bend sequence ordering, Geometry use identification, primary pin identification, and time stamps.
PCB Editor 17.4 QIR 1
PCB Panelization: Setup and manage your fabrication panels directly within PCB Editor (OrCAD Pro & Allegro Feature)
New Design Setup Workflow: You can now use the new Design Setup Workflow to prepare for analysis by setting up your design for the different checks. You can set up cross-section, DC nets, components, Xnets, and differential pairs. You can then save the design with the changes. As with all other work flows, you can access this workflow from the Analysis Workflows pane (Analyze – Workflow Manager).
3D Canvas Updates: A number of improvements and enhancements have been made to the 3D canvas
- Performance Improvements: In this release, performance improvements is a top priority resulting in greatly improved launch times and reduced memory usage.
- 3D Canvas Filter Dialog: You will see the re-designed filter dialogWith this redesigned dialog. You have the choice of selecting what layers to visualize in 3D Canvas – All Layers or Outer Layers only, and what objects you wish to bring into the 3D Canvas. You can now visualize much larger designs in 3D Canvas by eliminating memory straining objects.
- Nets Pane: A new pane has been added to 3D Canvas – the Nets pane. Prior to this release, nets were visualized on the 3D Canvas, but no underlying information regarding nets were imported. With this release, net information (names, type, properties, and so on) are also imported into 3D Canvas and the new Nets pane allows you to control how to visualize the nets in 3D Canvas. You can select All Nets (the default view) and any other groups of nets contained in a design.
- Variable Highlighting: Prior to this release, components selected on the 2D side or selected in 3D Canvas were shown in 3D Canvas as selected (red). With this release, two new highlighting choices are available – Dim and Vanish. With the Dim option, selected objects still appear on the canvas as red while the remainder of the elements are dimmed. With the Vanish option, selected objects appear on the canvas as red while the remainder of the elements disappear.
PCB Editor 17.4
IPC 2581 Spec Properties: By defining a SPEC that is composed of the fabrication notes, the notes become part of the IPC-2581 data and are directly read by an IPC-2581 viewing tool, reducing the need to locate the correct drawing or document to read the notes. Another example would be to define assembly notes for a heat sink to be added to a part. The assembly note might instruct users to add a specific thermal epoxy first, then add the heatsink after the epoxy is applied.
Mask Defined Pin Annular Ring Check: A new Mask Defined Pad check has been added to the Design for Manufacturing Annular Ring checks and the DesignTrue DFM Wizard template file. There are two common types of padstack definitions when it comes to soldermask to pin pad size ratios. The first, metal-defined padstack (sometimes referred to as non-mask defined padstack), is where the solder mask opening is typically larger than the pin pad. The other is a mask-defined padstack, where the solder mask size is typically smaller than the pin pad. The mask-defined pad is often used for BGA components to contain the solder ball within the pin pad and prevent outflow of solder.
Hierarchical Route and Via Keepouts: You can now define keepout by layer type and location using the additional Route and Via Keepout subclasses that have been added to Symbol Editor. Following a model similar to Constraint Regions, use the OUTER_LAYERS, INNER_SIGNAL_LAYERS, and INNER_PLANE_LAYERS subclasses to create keepout shapes.
Contour Routing Update: The 17.4-2019 release now supports the previous Enhanced Contour behavior as the default contouring method. In addition to the previously supported functionality of latching/unlatching and shoving, this release focuses on ease of use and power by adding additional spacing controls and full constraint region support.
Copy/Paste Update: In previous versions of layout editors, copying of objects was performed by selecting objects and pasting them to one location at a time. While the use model was simple, the functionality was limited. The 17.4-2019 release aligns the copying functionality of the layout editors with other popular software applications by adding familiar behaviors. This new copy command combines the precision of single click or single location pasting with the power of window select or multi-location pasting. As with most applications, copied objects are buffered for pasting at a later time. You can paste the last copied object at any time simply by using the paste command.
Copy: The Copy command now adds the selected objects to a buffer and automatically starts the Paste command to enable the placing of objects on the canvas.
Paste: The Paste command supports all legacy “copy” options as well as new support for shape net retention. In addition to these options, pasting can be used in two different manners.
Single Location Pasting
Copying of objects and pasting at one location per click
Object snaps to the singular selected object or location
Multiple Location Pasting
Copying of objects and pasting at multiple locations through window select
Objects snap to all selected objects
3DMechanical Symbol Transparency: Designers who wish to “peek” inside a PCB assembly encased with a mechanical cover can now do so. Now look through the mechanical cover into an assembly by setting the global transparency/opaqueness setting.
Unplated Holes in Footprints: Unplated holes in footprint (.dra) files can now be visualized when the footprint is brought into 3D Canvas. Previously, unplated holes were not represented.
STEP Models and Pastemask: In some system designs, such as complicated telephony devices, even the most minuscule space is critical. With the 17.4-2019 release, the position of 3D models can now be globally adjusted to take the thickness of solderpaste into account in the “z” direction. By default, the STEP model location in the “z” direction is the bottom of the model located directly on top of the copper pads.
PSpice 17.4 QIR 2
Usability updates. Get notified for missing parts for your PSpice models as you place them with Online DRC. Navigate warnings and errors with cross-probe between DRC and schematic. PSpice parts are loaded automatically when a new PSpice project is created. Improved capture integration with the ability to view PSpice models within Capture.
New modelling applications. Easy-to-use DIODE and MOSFET model parameters from device datasheet, specifically targeted for power applications.

PCB Editor 17.2 QIR7
Design for Fabrication Rule Enhancements: In the Design for Fabrication constraints, a new category Copper Features has been added in this release. This category applies rule to cover minimum line width, antenna, and acid traps.
Design for Assembly Rule Enhancements: A new category PkgToPkg Spacing has been added in the Design for Assembly constraints. You can now maintain the DFA table within Constraint Manager and assign different DFA rules based on stack up technology, specifically within rigid-flex designs. All existing functionalities are still maintained from previous versions.
Design for Testability Rule Enhancements: A new Design for Test constraints have been added in the Manufacturing category in the QIR 7 release. These group of checks are related to issues in the final testing of the PCB assembly.
DesignTrue DFM Ecosystem: To make designs ready for fabrication, the information about various manufacturing constraints and rules and the supported values are obtained from PCB fabricators in the form of spreadsheets. The spreadsheet is then transferred into Constraint Manager by a PCB designer. This process is error-prone and time consuming. The easiest way to obtain the rules would be in the form of direct import of fabricator rules into the Constraint Manager using technology files recognized by Constraint Manager.
DesignTrue DFM Web-Based Rules Request: The DesignTrue DFM Partner Program was developed to facilitate the request for fabrication rules directly from the supplier and receive those rules in the constraint technology file format. You can then directly import the rule files received into Constraint Manager.
- To request rules, open the request login site from a Web browser at https:\\pcb.cadence.com\dfm_customer.
3D Canvas Update: The recently productized 3D Canvas continues its growth and maturity with the QIR7 release. With additional features still under development, this release covers incremental updates that will enhance the user experience.
- Selecting a specific area of a design to visualize in 3D is now easier with "window select" on the 2D workspace
- The popular Cutting Plane feature has been supplemented with a "reverse cutting plane" option
- The original Perspective View has been paired with an additional Orthographic View choice
- The 3D Canvas now recognizes STEP model colors assigned in the STEP Package Mapper
- Color Theme layers now have transparency control sliders and objects falling within holes
- Cutouts and outside the board outline are now eliminated from view
Place Vision: Place Vision, available in PCB Editor, is a graphical environment designed to increase productivity and efficiency with various component placement strategies. While the concept is similar to Timing Vision, Place Vision offers guidance with respect to:
- Xnet rat filtering
- Timing driven Placement
- Component Association
Sigrity Technology Driven High-Speed Signal Analysis and Checking: OrCAD® Integrated Analysis and Checking is a new, unique environment blending the best of OrCAD® and Sigrity™ technologies that provides analysis and checking capability entirely within the PCB Editor framework. For rule checking, DRC and ERC capabilities continue to depend on Constraint Manager as the single cockpit. This release introduces two new workflow analysis capabilities for impedance and coupling. The workflows provide guided access to Sigrity analysis with results returned as dockable tables and plots, or as new Vision overlays.
Timing Path support for Z-Axis Delay: The Z dimension of Vias and Through Hole Pins can now be included in timing path DRC calculations.
Pin Delay Property for Extended Timing Path into Packages: System level constraints typically require the creation of a Design Link and possession of mating boards or package databases in order to create a multi-board constraint solution. A timing path from the die of one chip to the die of another requires the MCM file from Allegro Package Designer (APD) or SiP Layout to create the extended timing path. Obtaining these databases from Chip vendors is not always possible and the alternative for many was to create formulas in applications like Excel. The Pin Delay property allows external delay values like package length to be entered into the OrCAD PCB Editor and assigned to a component from a CSV file, assigned as properties/values to pin instances, or entered in the PIN Delay column of the Propagation Delay or Differential Pair worksheets in Constraint Manager.
Differential Pair Dynamic Phase Control: Differential Pair technology has evolved where more stringent checking is required in the area of phase control. This is evident with higher data rates associated with parallel buses. In the simplest of terms, Differential Pair technology is sending opposite and equal signals down a pair of traces. Keeping these opposite signals in phase is essential in assuring that they function as intended. As the current "Static Phase" is limited to a one time check across the entire Driver-Receiver path, the "Dynamic Phase" check performs phase checks at bend point intervals across the differential pair. The check is designed to meet the guidelines suggesting the path lengths of the true and complement signals within the differential pair must differ by no more than "x mils" along the entire path of the net. If at any point on the net, the skew between true and complement exceeds "x mils", this mismatch needs to be compensated within "y mils". Representative values for x and y might be x = 20 and y = 600.
Backdrill: The Backdrill application, originally introduced in the Allegro PCB Editor, has undergone some significant enhancements and now introduced to OrCAD Professional. Backdrill data is now stored in the library padstacks and utilized at the design level during the analysis and backdrill generation process. Padstacks which do not have predefined backdrill information can be automatically updated at the design level by the entering the backdrill criteria prior to running backdrill. Design layers which are backdrilled will have Route Keepout Shapes generated to ensure design integrity is maintained with separate padstack definition controls for the backdrill start layer, internal layer and negative layer anti-pad geometries without the need of custom padstacks or scripts. All backdrill data is available on the individual Pin/Via objects displayed on the canvas or by simply querying the object using Show Element, and generating the Backdrill Legends and detailed Backdrill Report. In addition, the setup time for backdrill can now be improved as a result of algorithms designed to create intelligent layer pairs.
Net Group Enhancements: The Net Group constraint object introduced in release 16.6 to replace the Bus constraint object has been enhanced in OrCAD Professional to support Nesting conditions. This may be useful in defining High Speed Interfaces
Design Previews: QIR 7 introduces design previews for a faster way of identifying and opening designs. Located on both the start page as well as the "open" dialog, users are now presented with a visual representation of their board files. Previews are generated and linked to the database with each save to ensure that they are always up to date.
New Board Creator: When starting a new board file, you are presented with a dialog allowing for quick and easy database setup. Using the same parameters as found in the Design Parameters dialog, you can adjust the database units, sheet size, accuracy, extents, and origin location for designs. As the you update or change the parameters, the dynamic preview located on the right side of the form updates to reflect the selections. The origin is represented by the location of the red dot.
PCB Editor 17.2 QIR6
New Design for Assembly (DFA) Rules: Newly added Design for Assembly (DFA) constraints are located under the Manufacturing category in Constraint Manager.
DFA Outline Rules: Outline checks for DFA provide rules for checking minimum spacing between component bodies to the DESIGN_OUTLINE and component bodies to CUTOUT subclasses. For every component, DFA_BOUND takes first precedence followed by PACKAGE_BOUND.
- Minimum spacing for pastemask to DESIGN_OUTLINE and CUTOUT subclass rules are also part of this category.
DFA Spacing Rules: Minimum DFA spacing rules for various mechanical hole types to component bodies, as well as component pins to other component bodies, are defined in Constraint Manager. Other spacing checks include pastemask to pastemask and pastemask to via minimum spacing.
DFA Pastemask Rules: Pastemask checks detect the annular ring of the pastemask to SMD copper pin pad, missing pastemask on any SMD pin pad, and pastemask to other mask openings, such as soldermask and coverlay.
STEP Package Mapping: The ability to remove the mapping of all STEP models to all symbols in a layout has been added to the Device/Package STEP Mapping dialog box. Click Purge button located in the lower center of the dialog box. A confirmation message displays.
STEP Export Options: An option to use the basic symbol geometry and ignore mapped STEP models for of a layout drawing to a STEP file has been added. Enabling the Ignore STEP model definitions option in the STEP Export dialog ignores the STEP models assigned to the package symbols during the export process. The place_bound height associated with those symbols are exported instead. Enclosure and assembly models are still exported as 3D STEP data.
Refresh Symbol Enhancement: You can now refresh symbols to the latest STEP models. A new option Update STEP mapping data only has been added in the Update Modules and Symbols dialog box.
Dynamic Shape Quality and Performance Initiative: Dynamic shape voiding has been improved in this QIR. Abnormalities referred to as "spikes" or "slits" in shapes are addressed. This enhancement reduces or eliminates the need to add oversize clearance properties as a workaround.
Place Replicate Enhancements: The MDD files can now be reused and replicated on boards with differing stackups. When a module stackup does not match the target board stackup, the layer mapping window appears. This window allows quick drag and drop operations to adjust and map the module stackup to the target board. Color coding helps to easily identify plane layers and signal layers. All via types are supported including through, micro, blind, and buried. Currently, all module layers must be mapped and reordering of module layers is not supported.
Route Clearance View: A new option Clearance View is added in the Options pane of the add connect command. When enabled, generates polygon around objects and displays the space available for routing in a channel.
Enhancements in Copy and Paste Commands: The Paste command now supports Retain net of shapes option that allows you to decide if the copied shape should retain the source net or inherits the net of the destination object. By default, this setting is enabled and source net is retained for a copied shape, which is the previous behavior.
Basic PDF Export: A non-intelligent PDF Export command that provides a method to print 2D PDF without tree structures and meta data is available in all OrCAD and Allegro layout editors. If the PDF Publisher license is not found, this version of PDF Export command becomes available.
Show Measure Update: Improvements has been made in areas of measuring to and from slots and embedded component mask pads.
Mechanical Hole Checking: A new design mode DRC, Mechanical Drill Hole Checks Use Hole Spacing Values checks mechanical pin to conductors spacing using layer-based spacing controls. This check restores the DRC to pre-17.2-2016 behavior.
Mechanical Pin to Mechanical Pin Spacing: is replaced by a more descriptive Mechanical Drill Hole to Mechanical Drill Hole spacing. Similarly, Mechanical Pin to Conductor spacing check is replaced by Mechanical Drill Hole to Conductor spacing check.
Zones with Placed Symbols: Now, you can edit or delete stackup of a zone that has placed symbols. You can modify the surface layers of the stackup. Modifying the stackup will update symbols and vias based on the layers defined in the modified stackup.
PCB Editor 17.2 QIR5
Start Page: A new Start Page is now part of the editor canvas in the form of a second tab in the workspace. The Start Page tab allows you to access information, such as best practice papers, migration information, tips and tricks, and provides easy access to recently opened designs.
Design Workflow Pane: To assist new users, workflows are introduced into a new pane called Design Workflow. This initial workflow can be used to guide users in performing basic tasks. The workflow eliminates the need to search for the necessary menu, toolbar icons, or knowing the command. Clicking any option in the workflow pane brings up the dialog for that command.
Frequently-Used Icons: You can now assign frequently used icons to access right-click context menu. A maximum of 16 icons can be added.
Customizable Design Canvas: It is now easier to customize the canvas design to meet your requirements or design intent. Different views can be tailored to different aspects of the design. You can create a view for placement and maybe, another for routing, and a third for checking and producing deliverables. Each view can be customized, saved, and recalled when needed, including locating panes on a second or third monitor.
Improved Graphic Response Time: To improve graphic redraw response time, particularly for large designs with many small objects, you now have the ability to control the granularity of the design objects at different zoom levels. A new Object Filter control is provided in the Color dialog. This new control reduces the visual complexity of large designs and results in quicker redraws, panning and zooming. You can customize the level of pin/via granularity using a slider, which allows you to set the level of zoom at which small objects will come into view.
Find by Query Update: The find_by_query command allows viewing of all the objects in the Find by Query dialog. You can query a design database for certain type of objects by filtering them based on associated properties. The resulting matching objects are displayed in a table. Selecting items from the results table selects them in the canvas.
Assign Net to Via: The command is available in General Edit and Etch Edit Application modes. It is now possible to assign a net to a via. Hover over a single via or select multiple vias, right-click, and choose Assign Net to Via option.
Via Label Enhancement: As HDI trends continue to increase, the via labels become more important in identifying the begin/end layers of buried/blind vias that are used in the design. Labels are sequentially numbered beginning from the Top (as layer 1) to Bottom (as layer N). This ordering is not always synchronized with the actual layer names and forces designers to create matrices to understand the mapping.
Padstack Editor Enhancements:
- Donut pads, are now supported on mask layers
- Copy and paste functionality has been improved. You can now copy and paste layer information between design and mask layers
- Auto-scrolling within the working grid has been improved
In-Design DFx: For PCB designs, design for manufacturing flow has traditionally consisted of creating fabrication data at the end of the design, which is then sent to the fabricator. Hours, or days later, the fabricator sends back a list of issues to be addressed. The issues are corrected, and the cycle of data creation is repeated, resulting in lost days in the design to fabrication phase.File Locking: The File Properties dialog box now supports five categories of data lock types. They include Manufacturing, Database, Logic, Constraints, and MCAD/ECAD. If a particular option is selected, then the export command belonging to that group are disabled. For example, enabling the Manufacturing option disables the export of 2581, ODB++, artwork, stream out, DFx check, drill legend, NC Drill, NC Route, and Variant options.
PCB Editor 17.2 QIR4
DRC Browser: The layout editors now include an advanced tool that enhances the ability to locate, review, and address DRCs. The DRC Browser UI contains various navigation, sorting, and filtering capabilities making it easier to focus on resolving design issues by DRC violation types and areas. The DRC Browser provides feedback on the number of errors, including bar and pie charts that are dynamically updated as issues are corrected or introduced, while editing the design.
The DRC Browser assists in correcting issues by providing:
- Windowing into the location of a selected DRC
- A tristate stsus of DRC violations (Read, Unread, Review)
- Various Navigation Methods
- The ability to assign the waive DRC attribute to a selected DRC
- DRC chart for graphical representation
Intra-Differential Pair Spacing Rule: A new Referenced Spacing CSet column has been added to the Physical Domain - Net and Region worksheets to allow the assignment of a specific Spacing constraint set to drive the minimum clearance between the via members of a differential pair. This Spacing CSet does not affect the spacing between the clines of the differential pair.MCAD Collaboration Environment: The MCAD Collaboration environment streamlines the ECAD/MCAD flow for IDX, reducing the concern for managing the multiple changes and modifications that occur during the design cycle. This environment is based on a shared repository where both the layout editor and MCAD tools read and write IDX files. The MCAD Collaboration environment:
Static Phase Control at Via Transitions: Default Static Phase DRC calculates the phase length from the Receiver Pins back to its designated Driver Pins. When the static phase constraint value is exceeds a DRC marker is reported at the Driver Pin. A new optional behavior will now perform the static phase length calculations from each differential pair via transition back to its designated Driver Pins, and report a DRC marker when the constraint value is exceeded. Any via type transition, thru, bb via, and micro will be checked as long as the differential pair members are transitioned from the same layer.
Dynamic Component Alignment: The dynamic component alignment behavior with snapping guidelines is similar to Microsoft programs such as PowerPoint. Designers can perform the one-two combination of placing and aligning components real time increasing their productivity and efficiency. Available during the Move command, the guidelines can be configured for either component origins, place bound edges, or both. You can also select, color of choice for the lines indicating the available snap points. This setting is located in the Color dialog Display folder.
Dynamic Ratsnest Update: The dynamic ratsnest behavior during component movement was introduced in release 17.2-2016 QIR 3. Nets that are user or system scheduled are ignored as are power and ground nets. Nets with a pin-count greater than 20 and components with a pin-count greater than 100 are also ignored to maintain performance during interactive.
Create Bounding Shape: Functionality for boundary based shape generation has been ported over from APD/SiP. Using the Create Bounding Shape command, you can now select pins, vias, fingers, and clines to create one or more auto-generated shapes based on the bounds of the objects selected. Shape creation can occur on multiple classes/subclasses simultaneously. Typical applications are expected to be for use with Bond Fingers, HDI technologies, as well as RF and high-speed applications.
Rigid-Flex Transformation (Bending): This QIR4 release builds upon the recently introduced Bend area capability on the 2D workspace by now allowing designers to transform - also known as bend - flex or rigid-flex designs from a flat 2D state into a transformed 3D state. Designers will now be able to visualize how their designs will look like when they are in their intended state. Designers also have the ability to add STEP models of housings and other such mechanical components to their PCB designs and check for fit and clearance issues.
Thieving with Hexagon Shapes: Thieving is typically added to surface layers to balance the chemical process for PCB plating. PCB Editor supports both surface, internal, and even mask layer thieving patterns. Hexagon shapes now supported in QIR 4 in addition to the legacy circle, rectangle, and line options. Enabling the Packed spacing option updates the spacing X and spacing Y fields providing a consistent spacing around a staggered hexagon pattern as shown in the following image.
Cross Section Chart and Table update: A new field Chart Unit in the Cross Section Chart dialog box permits table units to override database units.
OrCAD PCB Designer - 17.2 QIR#3
3D Canvas Update (View Video (link is external))
- 3D to 2D Move Command: In this release, this 3D to 2D interaction has been enhanced so you can move a component in the 3D Canvas and that change is reflected and updated in the 2D design
- Zone-Aware 3D: Zones now display actual thickness as specified in the Cross Section Editor
- 2D PDF and Export Dialog: A new Export dialog is added that can export a 2D PDF file
- Display of Silkscreen Text, Rectangles, and Shapes in 3D Canvas: In the previous release, component silkscreen outlines (lines) were visible; in this release, text (both reference designators and free text) is also visible on the 3D Canvas

Also, the reference designator for multi-packages is consistent (e.g. MP_2V5_REF will be MP_2V5_REF not MP_2V5_REFA).
Linking External Design Parts: Referenced parts of the external design can now be linked at the group or subgroup level.
CIS Performance Increase: The overall performance for CIS operations, especially when dealing with very large databases or queries, has been significantly improved.
Tcl Customization for CIS Explorer: CIS Explorer can be custom-configured with user-definable actions and capabilities. (For example, customized part placement checks can disable placement of an EOL part or provide a warning if part procurement has a long lead time). Query result rows can also be customized. (For example, rows can be highlighted blue for recommended parts or red for parts not recommended or allowed.)
CIS Multi-Value Support: Any CIS field can now be set as multi-valued for component instances with numerous information or content sources (e.g. lists for multiple datasheets/application notes or multiple PSpice models for a component).

OrCAD Capture Simulation Parameters: New Probe statement supports P() function to capture parameter values in .DAT file
PSpice - 16.6 QIR#3
Option to Apply Parasitics Globally: On analysis of a large number of OrCAD PSpice designs, it was found that a number of issues were caused by ideal devices (without parasitics). For example, using an ideal diode with parasitics can lead to convergence and performance issues as the simulator quickly moves to very small timesteps and often goes over minimum timestep thresholds. New options are available to set a minimum parasitics value level for diodes and Bipolar Junction Transistors (BJT) globally.
"10p files for Convergence Failure" Option: This option allows the operating point values even if a convergence failure has occurred, thereby avoiding situations where the user is left with previous bias point values on convergence failure
CSHUNT On/Off Option: In a number of cases, the nodes values do not stabilize because one or more feedback path has no delay in path. Successive iterations within OrCAD PSpice solver result in node oscillations and convergence errors. The OrCAD PSpice 16.6 QIR 3 provides a CSHUNT option that adds capacitors of specified value to the nodes. While a default value of 1.0E-12 is recommended, it can be changed on a case-by-case basis
Enable Continuation Methods: This series of transient convergence methods allows OrCAD PSpice simulator to override default solution search schemes and apply other heuristic algorithms, and is applied when all other options have failed. An example of such an algorithm is to reject the last successful time point and start working out the simulation solutions from the time point previous to the last successful time point. Additional heuristic algorithms will be added under this option in subsequent releases
Learning OrCAD PSpice Technology and Adding Your Own Content: A new chapter is available in the Learning OrCAD PSpice module. This chapter explains the steps required to add your own content, lessons, or app notes to OrCAD PSpice environment

These options include: bias-point convergence, voltage limiting, worst-case deviations, max-time step control, pseudo transient, and relative tolerance
Probe .dat Upgrade to 64-bit Precision: OrCAD PSpice technology now generates 64-bit data precision in the .dat file output. This ensures higher precision compared to the 32-bit .dat file data from previous releases. (As an example, in previous releases, when a very small amplitude voltage is superimposed on a large voltage, the resulting voltage lost its resolution in a 32-bit .dat file.)
UNDO Support for Captured Netlists: Netlisting to OrCAD PSpice environment now preserves UNDO, making it easier to make iterations and modify parameters, components, and connectivity
Enhanced IBIS Support: The IBIS to OrCAD PSpice model now supports V-T curves for all IBIS models up to version 5.0
Multi-core Engine Support: Enhancements to multi-core support and I/O read-write provide significant performance improvements. Focused performance enhancements, especially for large designs or designs with complex model instances (MOSFETS, BJT), also boost performance
Encryption Enhancements: Upgraded model encryption now includes 256-bit (AES) encryption support
Tcl-based Customization: Advanced Analysis, simulation, and .dat file access can be accessed and extended with user-definable actions and capabilities. This enables an environment that can be enhanced to specific flows and needs, and allows users to leverage enhanced features and design capabilities
OrCAD Capture - 16.5
Graphical Operation Locking (GOp): The GOp locking feature in Capture now allows you to lock the different parts of a schematic design. Lock objects on a page, folder, or even the complete design. This feature prevents inadvertently moving or deleting parts of a design that are locked. Designs requiring alteration will need to be unlocked before any changes are made.
Placement Report: Generate a report of the X and Y locations of the placement of the parts on a schematic. This report, generated as a .CSV file, provides details of the parts including; Reference Designator, Part Name, Schematic Name, Sheet Number, File System Location of the Part Library, and X and Y co-ordinate location.
Find Results Report: After executing the Find command on a design, generate a report for the results from the command. By running the Find command to search for different types of objects in a design, the search results display in different tabs of the Find window, allowing you to export the data from each tab.
Net Groups: OrCAD Capture introduces the concept of the NetGroup that allows you to create groups of nets. A NetGroup can include a group of scalar nets, vector nets, or a combination of both. Capture allows you to create Named NetGroups that can be used across a design or exported to other designs. Alternatively, for one-time use, you can create an Unnamed/Adhoc NetGroup. The new NetGroup Connector can be used to intelligently merge and tap out signals. It can also be used to generate net names for connected signals.
CIS.INI Settings: While the Capture INI settings are always dynamic, the CIS settings are more or less static and usually do not change after the initial CIS database related setup. You may often need to clear out and reinitialize your Capture INI settings, but may still want to retain the CIS settings. To allow this, OrCAD 16.5 now retains the CIS INI settings in a separate back-up file. This file retains the CIS INI settings that Capture will retrieve when it re-initializes the Capture INI settings.
Partial Design Simulation: The 16.5 release comes with the productivity enhancing feature of partial design simulation. You can now identify individual components of any design, and, using the partial design simulation feature, simulate only selected portions. Using this feature, you can simulate different circuits in the design with different simulation profiles. You can also netlist only a particular portion of the design. In addition, you can compare and merge portions of a design quickly.

Partial Design Simulation: This productivity-enhancing feature allows you to identify individual components of any design, and, using the partial design simulation feature, simulate only selected portions. You can simulate different circuits in the design with different simulation profiles, as well as netlist only a particular portion of the design. In addition, you can compare and merge portions of a design quickly.
OrCAD Capture - 16.3
Auto Wiring: In complex designs containing a large number of parts, the task of wiring the parts together is often a time consuming and tedious task. Wiring multiple pins to a bus can also be a tedious and repetitive task. Capture now includes an Auto-Wiring feature that allows you to wire two or more pins or wires on your schematic page. To wire multiple points on your page, you simply need to select all the points and choose the available Auto Wiring options (Auto-Wire Two Points or Auto-Wire Multiple Points). Besides wiring multiple points on your page, you can also wire points to a bus using the Auto-Connect to Bus option.
Associate Project Type: When you create a new project in Capture, you select the project type. After working on the project you may need to change the project type. For example, you may need to change the project type from Schematic to Analog or Mixed A/D type. Capture now includes the option to change the project type of any existing Capture project.
Design Navigation Improvements: Capture 16.3 now allows you to create Intersheet references on flat designs, simple as well as complex hierarchical designs. Design navigation in Capture now also includes signal navigation feature to navigate the connected signals on a design. This feature allows you to select a signal that you want to trace Capture then browses for all the connected signals on the design. Finally, you can select and highlight the signals from the browse list.
Wire Styling Options: You can now change the look and feel of a wire or a net on a schematic page by changing the color, line style or line width.
Color Part: Capture now allows you to alter the look and feel of the block to change the color of a specific block in your design. You can even add a picture to the block that acts as a visual representation of the implementation below the block.
Embedded Images: Now you can embed a large number of image types into a schematic page. The image types now supported by Capture include BMP, JPEG, GIF, PNG and TIFF.
OLE Object Support: OLE Object support in Capture allows you to embed or link an object on your schematic page. The object types that you are allowed to embed or link are defined by the applications and files available on your computer. This feature allows you to annotate your schematic pages with any external data (information) that you need to enhance the usability and readability of your design.
Bezier Curves & Elliptical Arcs: Capture now allows you to place elliptical arcs and multi-point bezier curves on your schematic pages.
PCB Editor 3D Footprint Viewer: The PCB Editor 3D Footprint viewer provides a three dimensional view of the footprint symbol of a selected part on the schematic or the part editor. Along with the footprint symbol, the viewer also displays pin numbers and pin names. On the viewer, you can view a footprint from different perspectives: top, bottom, front, back, left, right and isometric (a 120° angle view). Besides viewing the footprint, you can also use the 3D measure tool to measure any distance across the footprint canvas and across the x, y or z axis on the canvas.
User Defined Pin Shapes: You can now create your own pin shapes Capture. You then use these pin shapes when you create new part or if you want to edit the pins on an existing part. The pin you create can include any shape available in Capture including elliptical arcs and bezier curves.
Scripting Support: The 16.3 release of Capture includes a scripting functionality that allows you to execute a Capture command through a command prompt. Capture also provides the facility to store and later replay the command.
Locking Objects on Board & Schematics: The Capture - Allegro flow now includes an object locking feature. This feature allows you to temporarily lock and object on your schematic or board while you are cross-probing. This will help to avoid shifting (with the potential of breaking connectivity) of a component on the schematic or board during the cross-probe operation.
Output Warnings Filter: During PCB netlist creation, you now have the option to ignore many electrical constraints such as; PROPAGATION_DELAY, RATSNEST_SCHEDULE, DIFFERENTIAL_PAIR, NET_SPACING_TYPE, etc.
Power pin Enhancements: Capture now includes a new Assign Power Pins command that allows you define invisible power pins as NC pins. This ensures that you then only need to route the power pins that are not set as NC pins.
Electrical Rules: The DRC check in Capture is now separated out between physical rules and electrical rules. So you can now choose to run design checks from the available physical and / or electrical rules.
Check & Save: The new Check & Save option (available through the project manager File menu) allows you to run a DRC on the currently checked electrical rules in the DRC dialog. Since the DRC rules are defined by project, you need to define the electrical rules for a project and run the DRC check once on the current project. Subsequently, you can use this shortcut to execute the selected electrical DRC checks on the design.
OrCAD PCB Editor - 16.3
3D Viewer: The new 3D environment supports several filtering options; camera views; graphic display options such as solid, transparency, and wireframe; and mouse-driven controls for pan, zoom, and spinning the display. 3D viewing is also supported in pre-selection mode, making it possible to display HDI via structures or isolated sections of the board
Flip Design: You can now view the layout of the PCB from the bottom side. In addition to viewing, design edits such as moving silkscreen text can be performed while in this mode
Enhanced Pad Entry: Interactive etch editing has been enhanced to improve the transitioning of clines exiting and entering a padstack. The enhanced pad entry works on circle, rectangle, and oblong pads by exiting perpendicular to a pad edge, or exiting out a radius at an angle that does not produce an acute angle
Pastemask Clearance DRC: Pastemask-to-pastemask clearance check helps ensure there is sufficient solder paste gap between objects, preventing paste from shorting to other objects
Multi-Threading Support for DRC: Multi-threading support is integrated with the DRC system and supported on dual and quad configurations
Productivity Enhancements: Productivity enhancements include an enhanced windowing operation that permits a polygon selection window, customizable datatips through a user-configuration interface, and the measurement of the separation between any two objects, regardless of the layer, by the Show Measure menu
