  1. The AXI4-Stream interface is visible and is the only option for the Ethernet MAC+PCS/PMA and standalone Ethernet MAC core.
  2. The MII interface is visible and is the only option for the Ethernet PCS/PMA core.
  3. This feature is visible only for the Ethernet MAC+PCS/PMA 64 bit core configuration.
  4. This feature is visible only for the Ethernet MAC+PCS/PMA 32- bit core configuration.
  5. This feature is visible only for the PCS/PMA 32-bit core configuration.
  6. This feature is not yet supported.
  7. Default size of the statistics counter is 48-bit. To reconfigure this statistics counter, a hidden GUI parameter "STATISTICS_COUNTERS_SIZE" is provided. You can generate the IP using this parameter from the Vivado tcl console. Valid values are 32 to 48.
  8. The Number of Cores will be 1 only for the VersalĀ® devices and multi-core support will not be supported as GT will always be in the example design/outside the core.
  9. This support is available for non-Versal devices only.
  10. This feature is visible only for the Ethernet MAC+PCS/PMA 64-bit core configuration for:
    1. Disabled Auto-Negotiation feature or,
    2. Disabled FEC logic.
