Replacement for the discontinued MII to RMII IP core

Jump to solution

Hello All,

I have been trying to develop a core for Nexys 4 board, which uses RMII PHY interface. 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). However, I noticed that the MII to RMII core is a discontinued core. May I know if there is an alternative core? 

Thank you!

Hi @najath_akram ,

Unfortunately, we do not have a replacement core for MII2RMII.

Thank you very much. 

Is there any alternative way, or any example projects that I could go through to see, how to map MII or GMII interface to SGMII, RGMII and RMII ?

Hi @najath_akram ,

We have GMII2RGMII shim core for a GMII to RGMII interface. We also have PCS/PMA or SGMII core on PL for a GMII to SGMII/1000BASEX interface. For the latter, we have provided XAPP1305/1306 (for ZU+ devices) and XAPP1026/XAPP1082 (for Zynq) as reference design examples.

Hi @najath_akram ,

As a side note, the MII to RMII core is provided with all source files so you could potentially copy it in a custom directory and continue to use it with a newer version of Vivado.
