The Xilinx GMII2RGMII converter facilitates the conversion between GMII and RGMII interfaces in Xilinx devices. Since the design I am planning to use has an GMII interface, I tried using an RTL module to convert design interface from GMII to MII and then, the MII to RMII core in the IP catalog (shown below). The MII to RMII LogiCORE™ is a "shim" core which converts a traditional 16-pin Media Independent Interface (MII) on an AMD 10/100 Ethernet MAC core to a a 6-pin Reduced Media Independent Interface (RMII) interface, allowing the MAC to connect to RMII compliant PHYs. The details of PHY registers can be found in their respective documents. This core can switch dynamically between the three dierent speed modes. 0 and 1. 0, and SGMII can be created in the PL using the GMII/MII available on the EMIO interface. 5G BASE-X PCS/PMA" and after connect this IP to the "AXI ethernetLite" to facilitate programming. 3V or lower.
