The AXI4-Stream interface is visible and is the only option for the Ethernet MAC+PCS/PMA and standalone Ethernet MAC core. The MII interface is visible and is the only option for the Ethernet PCS/PMA core. The Base-R and Base-KR selections in the Vivado IDE use the same underlying PCS state machine. The Base-KR selection is a licensing gate that enables access to the Clause 74 FEC, Clause 108 RS-FEC, and AN/LT features. When FEC and AN/LT are disabled, the Base-R and Base-KR configurations produce functionally identical output and are wire-compatible with each other. Clause 74 (BASE-KR FEC) logic is not supported for Base-R. Clause 108 (RS-FEC) requires the BASE-KR license selection in the Vivado IDE. It supports only the 25G line rate and does not support 10G speed. Note: The Base-R and Base-KR selections use the same underlying PCS. Selecting Base-KR enables access to the FEC and AN/LT feature set and requires the EF-DI-25GBASE-KR license. The Statistics Counters are available in the register map and with block RAM when you enable the Include Statistics Counters option. Otherwise, the Statistics Counters is not available. Clause 74 (BASE-KR FEC) and Clause 108 (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. Soft RS-FEC TX, Hard RS-FEC RX option to reduce logic utilization by leveraging the embedded 100G RS-FEC function that exists within the CMAC block in UltraScale+™ devices. The Number of Cores is 1 only for the AMD Versal™ ™ devices and multi-core is not supported because GT is always in the example design/outside the core. Auto-Negotiation and Link Training is not supported for the Versal device family. If Use Legacy GT Wizard in Example Design is: 1 - Versal Adaptive SoC Transceivers Wizard (gt_quad_base IP) 0 - Versal Adaptive SoC Transceivers Wizard Subsystem (gtwiz_versal IP)
