Pin Discrepancies between OrCAD Capture and Allegro Pins on Translated OrCAD Layout PCB File

jaritter

I am working on a design which was originally done in OrCAD Layout (.max file).  I installed the translation utility and migrated it to Allegro.  (Currently running 17.2)  I have several connectors with mechanical (non-connect) mounting pins defined in the footprint, plus a BGA that has two fiducials in the footprint.  For each of those parts, I get the following message in netrev.lst:

#2   WARNING(SPMHNI-184): Device library warning detected.

WARNING: J9 component device pin number mismatch; cannot replace.

The only way I have found to work around this is to redefine the mechanical pins as connect pins and then add them to the schematic symbol.  This goes against our normal schematic symbol processes since non-connect mounting pins, fiducials, etc., are not supposed to appear in the schematic.  (As differentiated from, say, the mounting holes for a D-sub connector where these would typically be connected to chassis ground for shielding purposes)

Does anyone have a bright idea how to fix this between the Allegro footprints and OrCAD schematic symbols?

Thanks!

    Make sure that the pins in the footprint are indeed Mechanical pins (no pin number). If they do have a pin number delete the pin number text and save the footprint. If they are connect pins the pin quantity between the schematic symbol and the PCB Footprint MUST match. The Netrev.lst should list the actual pin mismatches so you can see where the issues are.
