hello karesz,
is there a spreadsheet import feature in PCAD?
in some other design software, like cadence concept and capture, there is an option to import a pre-formatted excel spreadsheet containing pin names and pin numbers to automatically generate the schematic symbol, then manually shift the pins to look like you want it to look like.
another option is, if you can get an orcad library or schematic design from xilinx, you may be able to import it to PCAD.
