  • Port Groups. Support for port groups or an interface port on a hierarchical symbol that corresponds to a net group used in the lower-level schematic. 
  • Variant Operations in Design Entry HDL. Variant-related tasks such as creating, editing, and deleting variants, marking components to variants, replacing components in a variant can now be performed in Design Entry HDL itself. 
  • Replace Component Validation in Variant Editor. When you now replace a component in Variant Editor or in the schematic variant view, Variant Editor checks whether the two components–the component that is being replaced and the component that will replace the selected component–have the same or compatible footprints, that is, JEDEC_TYPE properties. If the footprints are not compatible, a warning message is displayed.

Version 16.5

Products Covered: Allegro Layout Editors | Capture | Allegro Design Entry HDL

Allegro Layout Editors

16.5

  • Embedded Component Design: Enhancements including updates to Licensing, Front to Back Flow Support, Setup, Key Terminology, Design Rule Checks, and Best Practice Paper.
  • Graphical User Interface: Updates including Highlighting With Stipple Patterns, Dynamic and Static Shape Display, Highlighting Fixed Objects, Status Bar Updates, 3-D Viewer Update, Data Tip Setup, and Data Tip Display. Etch Edit Enhancements. Upates to Differential Phase Tuning, Trace Tapering, Group Route Via Patterns, Diff Pair Routing -, Transitions at Region Boundary, Pad Exit Behavior, HDI Via Labels, HDI Via-Via Line Fattening, Delete Via Structures, and Copy/Move Stacked Vias.
  • Intelligent PDF Output: This tool exports Allegro board data in a PDF document with intelligent data for components, nets, and test points. You can specify the graphical Class/subclass layers that can be viewed and the properties that are to be extracted in the PDF.
  • Associative Dimensioning: The Allegro dimensioning capabilities have been enhanced so that when a dimension is created involving one or more design database objects, internally, the dimension remains associated with these objects. Subsequent editing operations, such as the moving of an object, can then appropriately and automatically update any dimensions that are associated with that object.
  • Design for Manufacturing: Updates include DFA Enhancements (Side-End and End-Side support), DFA Usability, Minimum Metal to Metal, Clearance DRC, Duplicate Drill DRC, Cross Section Chart, and Backdrill Enhancement (Any Layer to Any Layer).
  • DRC Updates: Starting this release, the behavior of the Max Neck Length DRC is changed. Now the DRC flags an error if the cumulative length of necked sections exceeds the prescribed Max Neck Length value.
  • ECAD-MCAD Flow: Incremental data exchange with IDX.
  • Database and Misc Enhancements: Updates include Database Locking, Multi-threading Support, DBDOCTOR, Downrev to 16.3, DBSTAT, Same Net, Constraint Set update, Symbol Editor, Refresh Symbol, Modules and Locked Property, Techfile, Design Status, Color, Artwork, Thieving, Create Detail, Display Measure, Shape Copy, User Defined Mask Layers — Mirror support, Place Replicate — Support for Single Symbol, Placement Files, Design Partitioning, Polygon Select, Undo/Redo Buffer, Capture Canvas Image, Zoom Button in Pick Dialog, New Variables, New Properties, Modified Properties, Deleted Properties, Reports, IDF Out, Symbol Export, Data Migration, Script Migration, and Skill Enhancements.
  • RF PCB Enhancements: Updates include Usability Enhancements, IFF Interface Enhancements (Layer mapping for non-etch layers, Hierarchical component importing, RefDes Auto-synch) and Layout Enhancements (Breaking RF Components, Inserting RF Components, Converting RF Components, Shape to Component Enhancements, RF Push Enhancements).

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.

Allegro Engineering Data Management

Allegro Engineering Data Management

A collaborative environment, improving design team productivity by up to 50%.

Request Info

Common Library and Design Data Interface

Maintain a central master library of preferred parts and associated known-good library data which is automatically distributed to various design sites as new parts and updates appear in the library.

Configurable Environment

Enable a common cross-organization, cross-company methodology by defining standard design flows ensuring that important steps and check-points are not overlooked.

 

Parametric Component Search

Easily search your company’s preferred components database to identify approved and preferred parts—helping to lower costs and manage inventory.

Reduce ECOs

Greatly improve the design revision process—reduce the number the number of design ECO’s by verifying the accuracy of logical symbols and physical footprints using automatic library part validation.

Enterprise PLM Integration

Integrate directly with corporate PLM systems, providing work-in-progress (WIP) data management—helping with facilitate team collaboration by letting users control change adoption and maintain design revision history.
