Orcad CIS 16.3 to Allegro 16.3 pinswaps not working

ghurley

I need an EXACT step-by-step sequence of how to properly apply pinswap properties on different banks of a multi-symbol FPGA so that I can swap pins (and diff-pairs) in Allegro, and then back-annotate the swaps back into Orcad.

It's been so long since I've done this that I can't remember how to do it properly, and the current approach that the engineer is using on the schematic is not working.

i.e. what EXACT property is applied to pins in the schematic symbol, and what EXACT properties have to be built into the Allegro footprint in order for the device file to work properly?

I can't find good enough directions in the help files.

Thanks!

    Pin Group is the Capture library property that controls Pin Swapping, for the Section to Section swapping, you need to add the SWAP_INFO property and list the sections that you want to swap pins between. See Chapter 14 of the Capture Users Guide, cap_ug.pdf in the doc\cap_ug directory of the installation.
