Connecting multiple FPGAs?

[Tyrving]

Not an expert, but I see no reason why this would not work. Your bandwidth would be limited by the frequency of i/o writes and number of i/o pins you use - in the gigabit/sec range, but still lower than something you could achieve within a single fpga fabric. Reliability and lack of shielding using extraneous wires might be an issue at high frequencies, but also might work fine. Buying a bigger FPGA, using external (non-fpga) ICs for simple tasks might give you more LUTs to play with. What type of project are you working on?

Hope this helps,
