The 128-bit Straddled AXI4-Stream is visible and option for Ethernet MAC+PCS/PMA with 40G and 50G line rate options. The 256-bit Regular AXI4-Stream is visible and option for Ethernet MAC+PCS/PMA with 40G Line rate only. The MII interface is visible and is the only option for the Ethernet PCS/PMA core. Clause 74 (BASE-KR FEC) logic is not supported for Base-R. Clause 91 (RS-FEC) is not supported for Base-R, 40G speed. Clause 74 (BASE-KR FEC) and Clause 91 (RS-FEC) both can be selected in Vivado® IDE but during functional operation only one can be enabled at a time using the respective control signals. GTM integrated hard FEC. Only applicable for Devices with GTM (Not applicable for Versal® ACAP). The Statistics Counters are available in the register map only when you enable the Include Statistics Counters option. Otherwise, the Statistics Counters are not available. Statistics Resource Type block RAM option will be provided in the future release. There is only single core support for Versal ACAP. Multi-core is not supported as the example design has GT outside the core.
