single FPGA as TXR and RXR

Hello, I have just been exposed to working with FPGA. I want a single FPGA to act as the transmitter(say, generates bits) and as a Receiver(say, to test for bit error) . How do I make the fpg...

That is very simple then. You already done something like that but you were not sure about rx ready signal.

Your prbs1 sends data, add some dummy delay e.g. few registers in the way and send in parallel a valid out signal delay as data

your prbs2(copy of prbs1) waits for valid out and runs.

compare delayed data(received) with prbs2 output.
