RGMII MODE ethernet loop back program for cyclone 5 GT evaluation board

Hi

I have cyclone 5 gt evaluation board.

I want to check loop back test from board to my PC.

I added triple speed Ethernet ip core in quartux-2 but it is not working,i attached my verilog code.

can anyone have reference program for simple Ethernet loop-back test by quartux2 ?

Thanks
