      Check out some of the top reasons to upgrade to the new OrCAD 16.6, then vote on which additions you think are most valuable! Your votes help us decide which features should receive priority as we continue to educate users on this release. Thanks for participating!

      OrCAD Capture Top Reasons to Upgrade
      • Full Pin Control in Symbol Editing- Build, edit, and modify your symbols your way. Release 16.6 gives users complete control to modify symbol attributes including pin location at both the library and individual instance levels.
      • Integrated Signal Integrity Flow - OrCAD Capture 16.6 provides a new SI flow making it that much easier and more productive for engineers to perform early signal quality analysis during the design phase, including generating and embedding design constraints determined from simulation results directly into the Capture schematic.
        SI Flow Video
      • Custom DRC's - Expand on the standard Capture designs rules by adding your own. Define, configure, and run user specific DRC checks with OrCAD Capture 16.6.
      • Faster Part Searches - You will be amazed at how fast your Capture CIS database searches are in release 16.6. Whether you have 100 parts or 10,000, searching your parts database provide almost instantaneous results.
      • Multi-Version Viewing - Release 16.6 allows you to save your designs to older versions if needed AND view designs generated in older releases WITHOUT changing the file version. This maintains complete backward compatibility with your less progressive colleagues.
      Detailed Version History

      PSpice Top Reasons to Upgrade
      • Multicore Support - PSpice 16.6 takes advantage of the additional processing power available in multi-core CPU’s to help you get your analysis completed in record time.
      • Quicker Simulation Setup- Not only is the new PSpice 16.6 faster with multicore support but it is also much easier to setup and run your simulations. Release 16.6 adds new capabilities like the Place PSpice Part command which allows you to quickly select and place common PSpice elements for simulation.
      • Improved Convergence - Cadence engineers put a lot of work into making sure PSpice 16.6 converges on even the most sophisticated analyses. If you do run into issues, PSpice auto-convergence can now be executed during run-time allowing you to automatically adjust your settings for optimal convergence and continue your analysis.
      • Easy What-If Analysis - Simulation and analysis is often a very iterative process. PSpice 16.6 makes this kind of what-if analysis much easier by including PSpice simulations as undo / redo items (previously running a simulation would clear the undo / redo stack).
      • User Customization - Cadence has opened up PSpice for customization using the popular Tcl framework. Easily define and string together multiple simulation runs across multiple conditions, apply custom algorithms or equations to your analysis, even develop new ways to plot and analyze your data.
      Detailed Version History

      OrCAD PCB Editor Top Reasons
      • Inline Net Names - Sometimes little things can make a big difference, like the Inline Net Names in PCB Editor 16.6. By placing the names directly on the nets you can easily see which net you are working on without having to scan the screen, and avoid confusion.
      • View, Share, and, Collaborate in 3D - View and share your design in full 3D with STEP model support in OrCAD PCB Editor. Collaborate effectively with your mechanical counterparts using the new IDX format.

      • Updated Shape Editing - Not only do dynamic shapes now support multicore proccesors for even faster pour and heal they are easier to create and edit with parameterized cornering, quick expand/conract, and improved circle drawing to name a few.
      • Interactive Routing Updates - Interactive routing in OrCAD PCB Editor continues to expand its lead over the competition.  Release 16.6 provides updates like: Enhanced Slide Support, Smart Layer Add Connect, Visible Rats Control, and more.

      Enhanced CIS Explorer Functionality in OrCAD Capture CIS 16.6

      By Jeff Imes, Applications Engineer, EMA Design Automation

      Over the many years I’ve been using Capture CIS in both my design career and being an AE, I’ve always had a need to visually see the status of a certain part and restrict data from the CIS users like military and commercial parts availability for selection and placement. This was always on my wish list, but never appeared over the many years. Finally, it has become a reality.

      Through the new CIS TCL interface commands, you can now assign a color for any part database value in the CIS Explorer and filter out any part for placement. Also, the user can add more than one selectable value in ANY database field available in CIS.

      CIS Data Filter

      Here are a few examples of a situation that would require the CIS Filter:

      Example 1 for CIS Data Filter:

      CIS is being distributed globally throughout the corporation. The company wants to use one CIS database at HQ, but each division wants to have only access to the parts that are to be ordered  from that region.

      Example 2 for CIS Data Filter:

      I have a field in CIS (let’s say “ABC”) that specifies two types of parts (“Commercial” and “Military”). I want both part record types to be managed in the CIS database, but I only want “Team A” user to place “Commercial” Parts and “Team B” user to place “Military” parts.

      Example 3 for CIS Data Filter:

      In my CIS database I have a “Lifecycle” field that can contain “WIP”, “Released”, and “Obsolete” for values. If any record contains the “Lifecycle” field value “Obsolete”, the CIS explorer would not display these parts. But, the CIS database will still have the “Obsolete” record maintained.

      Once the TCL command with the data field and value set, the CIS Explorer will ignore and filter from the user’s view and use. In the following image, you can see the post results of the filtered data.

      Filtered Data in CIS Explorer 

      Example TCL Command:

      AddCISCriteria {Company Part Status} {=} {Obsolete} 0 0 0

      Color / highlight CIS row
      To highlight CIS rows, the TCL command would be set similarly to the CIS Data Filter with a few different settings. The row and font color can be applied to those parts that meet the criteria in the TCL command. Here you can see how colors can be assigned:

       Highlight CIS rows

      Example TCL Code Command:

      AddCISCriteria {Company Part Status} {=} {Production} {1} [CISGetColor 255 255 255] [CISGetColor 85 107 47]

      Multivalue Configure multi-value support for CIS fields

      In previous versions of Capture CIS, only the schematic part and PCB Footprint field would allow fully functional muli-value support. With the new CIS 16.6 release, TCL commands have been added to allow any available field the capability to have a drop down pick list of multiple values.

      <!--[if !supportLists]-->•       <!--[endif]-->e.g. enable dropdown list for datasheets

      <!--[if !supportLists]-->•       <!--[endif]-->e.g. display more than one PSpice model          

      Example TCL Command:
                                                      SetCISMultiValuedField {DataSheet}

      For those companies requiring more visual part selecting and control over their CIS data with Capture, it is now available in 16.6 to achieve this functionality. I have only touched on a few of these samples. There are many others that can be provided through the TCL interface.

      Stay tuned for future blogs from other AE’s like myself on the many other added OrCAD capabilities!
