Need help routing a 4 layers PCB
« on: July 28, 2017, 08:20:26 AM »
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.

Trenz Electronics manufactures exactly what you need. Go check out their website.

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.
