Ethernet GMII to RMII converter ip

Hello, Ethernet RMII Interface on the cyclone V board is connected through FPGA IO, to use one of the HPS EMACs we need GMII to RMII converter ip. Can anyone help with the Ethernet IP to ...

    Hi snehal_p,


    Although the HPS EMAC supports RGMII(dedicated hps part pin), you can try route the EMAC to the FPGA in order to re-use the HPS I/O for other peripherals. When the EMAC is routed into the FPGA it is exposed as a MII/GMII interface. So when the EMAC is routed into FPGA, it support GMII interface.

    Hello Zi Ying,

    Thanks for the response.

    On cyclone V board we have Ethernet RMII interface through FPGA IO.

    As when the EMAC is routed into the FPGA it is exposed as a MII/GMII interface. So when the EMAC is routed into FPGA, it support GMII interface. Can you suggest GMII to RMII converter ip.

    Thanks,
