fail to compile after assigned the SFP_TX_P1 of SFP+ module (arria V gx dev kit)

Thanks Eduardo, I think in my case the problem was solved by keeping all the pins constrained to one region. I had to move the LVDS to another connector. I had originally assumed that all of the LVDS RX pins brought to the headers were from the same bank but that was not the case. I wish the error would have been more clear, but I am past it at this point.
