The following figure shows the MRMAC FEC Only example design simulation. In the block diagram, the MRMAC FEC Only example design uses a pseudo-random binary sequence (PRBS) based packet generator and monitor to generate and check Ethernet traffic. A test bench controls and monitors the packet generator and also configures the MRMAC IP through an AXI4-Lite interface.
