17.4 Design Sync Fails without providing errors

DDPCB

As the title suggests I am unable to perform design sync between OrCAD Capture and Allegro. When I add a layout and try to sync to it I am given ERROR(ORCAP-2426): Cannot run Design Sync because of errors. See session log for error details.

This issue started to occur after I changed parts that exist on previously created PCBs. I changed the following leading up to this:

1. Added height in Allegro to many of my components using the Setup->Area->Package Height tool.

2. Changed the reference designator category in OrCAD Capture to TP for several components on board.

Any advice here would be most welcome. Thanks!

    Hi Steve! The netrev.lst file I found in this folder is from the original design sync performed last year and indicates no errors. If I remove this netrev.lst file from the directory and then attempt to design sync again another instance of the file is not generated and I am issued the same error. Is there something specific I should lookout for in the netrev.lst I have besides the error list or is there another path I should investigate? I notice that the design sync is failing on multiple boards as well, not just this one.

    OK try opening the board in PCB Editor and Import the netlist the manual way and see if that produces a netrev.lst / detail of errors.

    I generated the netlist in OrCAD Capture, and successfully imported it into Allegro. The netrev.lst generated in this way indicates no errors, oversights, or warnings detected but when I save the board file, close Allegro and return to OrCAD Capture to design sync I am issued the same error.

    OK try opening the schematic in OrCAD Capture then try PCB - New Layout, for Import Board File and Board use the board file you have and then see if that works. If it does now make a change and see if you can run Design Sync. Also make sure you are up to date in regard to hotfixes (currently 17.4-2019 S024).

    When I attempt to use the New Layout functionality OrCAD Capture crashes (hangs indefinitely until forced close). This occurs with various combinations of Input Board and Board (including your suggestion of using the one board file for both fields). This also happens if I use the default board directory or the directory for the layout of this board. Currently trying to get the most up to date hotfix but have to call the support number for assistance so I can properly log in with my company license so will be some time.

    I am currently on version 17.4-2019 P001 for reference (not sure if that would cause this).
