DBC2C20_MII to RMII

Hi all.

I have an EBV DBC2C20 Evaluation Board with two ethernet phy.

I have tried some IP ETH_MAC CORE, but I have a problem.

My FPGA comunicates with ETH_PHY through RMII interface but the ETH_MAC comunicates through MII.

I have need an MII/RMII converter.

Is there an VHDL code for this converter?

I have already seen on opencores.org, but I have not found!!

Do you help me?

Thanks :)

Timo
