Transceiver Block Assignment

Hi,

I am trying to map my signal connection from the Arria-II GX FPGA onto the HSMC connection port. However, I am having trouble mapping the connection between the transceiver block within the Arria-II FPGA onto the output pins. I know the connection pins that maps to the external HSMC connector from the FPGA (U33, U34, T31, T32, R33, R34, etc.), but I do not know from which specific transceiver block should I connect to which pin. The device that I am using is the EP2AGX125, which contains 3 transceiver blocks, so how should I map from these 3 transceiver blocks to the output pins?

Thanks,
