Need help routing a 4 layers PCB
« on: July 27, 2017, 10:20:26 pm »
Hi everyone,

Could someone give me a hint on routing this 4 layers FPGA PCB?

It's a small board (1" X 1.90") with lots of wires (303 airwires)

Please see attached the schematics and board files from eagle, with components already assembled.
I tried to wire it manually but I found 303 airwires too much to do it manually on a small board.
I used eagle autoratorators but I'm still left with 26 airwires.

Thanks,

Chris

All due respect, if you cannot accomplish this, then you've bitten off more than you can chew.

I will gladly help you. The official, government approved rate for an engineer contracting work goes for 350 USD / day in my home country. PM me for details.

I'm sorry if it seems like we are being rude, but this is a non-simple problem that people get paid a great deal of money to do correctly. Designing a board for a moderately sized FPGA is several steps below the design of a modern PC motherboard, with high end, 3000+ pin FPGAs being several steps above. This is the one point that has kept me away from FPGAs. Who cares if I can design a full processor on an FPGA development board if I cannot possibly transfer the FPGA to my own designs.

This is one area that, for hobbyists, is a case where if you cannot do it yourself, you're not ready.
