I'm working with with the Virtex-7 FPGA (VC707) and want to be able to test the circuits our lab designs in runtime with the FMC I/O ports. I have very little experience with this board and it's capabilities and have had little luck in finding documentation on using the FMC ports for runtime circuit testing. Our aim is to be able to read inputs from our circuits and have those signals drive outputs to the circuit we are testing. Our digital circuits use a handshaking protocol that requires this function. Does anyone have experience with this or know where I can find a detailed tutorial on using the FMC ports for testing?
