2.4.4. Test Case—Design Example with the IEEE 1588v2 Feature

Note: For 10G/25G Ethernet single-channel design example with IEEE 1588v2 feature simulation testbench, refer to Figure 7.

The simulation test case performs the following actions:

  1. Instantiates 25G Ethernet Intel® FPGA IP, ATX PLL, and IO PLL (sampling 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. Checks for 10 valid data on 25G speed.
  6. Switches to 10G speed.
  7. Waits for RX clock and PHY status signal to settle.
  8. Prints PHY status.
  9. Checks for another 10 valid data on 10G speed.
  10. Switches to 25G speed once all 10 valid data passes.
  11. Waits for RX clock and PHY status signal to settle.
  12. Prints PHY status.
  13. Checks for another 10 valid data on 25G speed.
  14. Analyzes the results. The successful testbench displays "Simulation PASSED." when the PTP delay and offset data is within the threshold value.

The following sample output illustrates a successful simulation test run:
