I'm very interested in this area, but haven't actually done anything beyond surf the web looking for something that fits my budget and interests. I think a major part of the problem is that bleeding edge silicon technology as used by up-to-date FPGAs doesn't fit with 5V PCI. (The specs call for 11V spikes when the reflections are out to get you.) Most PCs have 5V PCI slots because most PCI add in cards are keyed for 5V slots. I haven't seen any motherboards with 3V only PCI slots, but maybe I'm not looking in the right place. In any case, I haven't seen any Xilinx development boards setup for 3V only. My straw man is to find an inexpensive board with FPGA and not much else that will plug into a PCI slot. I'm expecting to have to build a small daughter card with a few coax connectors, level converters and whatever. Maybe the right answer is to wait until cheap PC motherboards have PCI-express slots. (Servers have already switched to PCI-Express.) The best I've found so far is a Spartan 3 on Raggedstone1 http://www.enterpoint.co.uk/moelbryn/raggedstone1.html But the connectors don't have any ground pins and there aren't any mounting holes. -- These are my opinions, not necessarily my employer's.
