Here is the problem. I have schematic where I have 484 pin FPGA. It is drawn in Allegro Cadance schematic capturing. So, to tailor it to my need i swapped pins around on FPGA (schematic reuse). Next what happen is we needed to go to same part but different part number for FPGA. So, after i used modify command, i lost all swapped pin locations. I still have a copy of old schematic backed. Is there is a way to modify some "file" or locations in some of the files using backed old files to fix it easy without going and swap pins manually? I usse cadence v 16.5.
I have run into the exact same issue and never found a simple solution. I used the packager and Allegro files to extract the pin assignments (after the swap). Then I extracted the schematic pins and did some fancy lookups in Excel and created a new pin map. This allowed me to create a static symbol of the FPGA with the new pin assignments. Was a bit of work.
