Test Scenario for Design Example with IEEE 1588v2

To perform test case, follow these steps:

  1. Set the start up with channel configured to 10G mode.
  2. Perform basic MAC configuration, PHY speed configuration, 1588 component configuration and PTP clock mode configuration for all 2 channels.
  3. Wait for the design example to assert the channel_ready signals for all 2 channels.
  4. Send the following packets:
    • Non-PTP
    • No VLAN, PTP over Ethernet, PTP Sync Message, 1-step PTP
    • VLAN, PTPover UDP/IPv4, PTP Sync Message,1-step PTP
    • Stacked VLAN, PTP over UDP/IPv6, PTP Sync Message, 2-step PTP
    • No VLAN, PTP over Ethernet, PTP Delay Request Message, 1-step PTP
    • VLAN, PTPover UDP/IPv4, PTP Delay Request Message, 2-step PTP
    • Stacked VLAN, PTP over UDP/IPv6, PTP Delay Request Message, 1-step PTP
  5. Repeat steps 2 to 4 for 1G, 100M and 10M speed mode.
  6. When the simulation ends, refer to the transcript window for channel 0 MAC TX and RX statistic counter results.

  7. If channel 0 Avalon_st RX interface successfully receives all 28 packets, the transcript displays PASSED.
