Hi guys, I have been using Easy-PC for a number of years as part of my electronics hobby, but only for pretty simple designs. I now have a few projects in mind that need FPGA's and/or modern processors in high-pincount BGA packages. Unfortunately I've come a bit unstuck at the component entry stage...
One of the advantages (or problems depending on your point of view) with FPGAs is that they don't have a fixed pinout apart from power pins etc. I can get nice ASCII pinout tables from the Xilinx-FPGA software, but I can't see an easy way to import them into Easy-PC.
I have tried to import them in CSV format, but I don't seem to be able to do that unless I can cope with a single 'gate'. This results in schematic symbols with 200+ I/O's which are pretty unmanageable IMHO.
I also don't seem to be able to get the pin-naming in row/column format quite right - the row/column offsets don't seem to stay at 1 when I edit them.
So, I guess my question is what's the best way to enter very large multi-gate components (200+ pins) from a pinout in ASCII form?
Cheers,
Joe.

Hi John, thanks for the reply!
It is interesting you suggest Eagle libs. I have had a quick go at importing some pre-existing Eagle libs, and it does seem to be possible to import multi-gate components.
I guess this is a question for the chaps at Number One, but is the Easy-PC .eil format documented anywhere, or would I have to do : Xilinx ASCII output --> scripting-magic --> Eagle lib --> Eagle Export as .eil --> EasyPC import?
Cheers,
Joe. |

Anyone got a good FPGA flow?
