My research group is building a mezzanine card that contains a lot of critical nets. We have four 500MHz DSPs and a V2P FPGA all connected together in a network. Each DSP also has access to SDRAM. Can anyone suggest a PCB design house that would route the board for us, someone used to dealing with signal integrity of many high-speed digital signals in smaller form factors? If at all possible, we would prefer someone in Illinois or a consultant that could come to Illinois.
