Stratix IV GX Pin Assignment

Thank you Daixiwen for your help,

Now that I put my signaltap to trigger on the mdio_oen = '1' and mdio_in = '0' I do have an answer coming from the PHY which is a small acknoledgement bit in the mdio_in.

I guess my PHY is communicating with my TSE but what do you mean by focus on the SGMII again?

I haven't done anything for the SGMII since I thought all the data coming out from the TSE were going to the PHY with the TX_p pin.

I finally trusted the schematics and put the PIN_AC31 instead (anyway I had errors with the D31).
