I use Excel to create the data and import it into the Symbol Editor in Library Manager. Use File/Export Pins to see a sample of the data. With practice you can make a 1700 pin FPGA in one day, including checking (copying and pasting from the datasheet directly)
There are 2 tools you can take into account: I/O Designer (it is more than just symbol wizard - it is poerful tool to integrate FPGA/FPGAs in your PCB design) and FPGA Symbol Creator. Regarding to I/O Designer it offers Symbols Generator to create set of symbols automatically and also it can work in special mode called Librarian mode (flow). I/O Designer allows you to export both symbols and PDB (part data) exported directly to Central Library.
If you have more questions please let me know.
Mentor acquired that capability with the Valor Computerized Systems merger. The entire development team which developed that capabilities is no longer is with Mentor Graphics. I personally know the developer. It has taken him about a year, and he has started a new venture. You can find more about the capability by searching the web for “EDA Builder”.
I/O Designer only will work for FPGAs and ASICs, It will not work for other large pin count parts. We're looking for a solution that works for all parts, not just a subset.
I think it was poor judgement on Mentor's part to discontinue development on the Valor symbol editor. It sounds like it was a good tool.
Thanks for the info, we'll put this tool on our list as another one to look at.
