2.6. Single Root I/O Virtualization (SR-IOV) Design Example Simulation Testbench

The simulation testbench instantiates the SR-IOV design example and a Root Port BFM to interface with the target Endpoint.

The test program writes to and reads back data from the same location in the on-chip memory across 2 PFs and 32 VFs per PF. It compares the data read to the expected result. The test reports, "Simulation stopped due to successful completion" if no errors occur. The SR-IOV design example supports Gen4 x16 Endpoint.
