2.4.3. Test Case—Design Example Without the IEEE 1588v2 Feature

The simulation test case performs the following actions:

  1. Instantiates 25G Ethernet Intel® FPGA IP and ATX PLL.
  2. Starts up the design example with an operating speed of 25G.
  3. Waits for RX clock and PHY status signal to settle.
  4. Prints PHY status.
  5. Sends and receives 10 valid data on 25G speed.
  6. Performs channel reset and switches to 10G speed.
  7. Waits for RX clock and PHY status signal to settle.
  8. Prints PHY status.
  9. Sends and receives another 10 valid data on 10G speed.
  10. Performs channel reset and switches to 25G speed.
  11. Waits for RX clock and PHY status signal to settle.
  12. Prints PHY status.
  13. Sends and receives another 10 valid data on 25G speed.
  14. Analyzes the results. The successful testbench displays "Simulation PASSED.".

The following sample output illustrates a successful simulation test run:
