In BIST mode, the demonstration test bench performs these steps:
- Input clock signals are generated.
- A reset is applied to the example design.
- The required Ethernet MAC bit rate is selected.
- The MDIO stimulus/response block responds to a read with all 1s indicating no PHY is present.
- The pattern generator(s) and checker(s) are enabled.
- The simulation runs for a fixed duration, allowing a large number of frames to pass.
- Any detected errors or lack of RX activity are reported as errors.
- If the AVB endpoint is included, the bandwidth of the two data streams is reported.
