adding pcie_xcvr to bts_general (Cyclone IV GX FPGA)

Hi There,

I am trying to add PCIE feature (the one we can find in bts_xcvr project) to bts_general.

The module, pcie_xcvr, can be added to the SOPC builder and generate successfully.

However, when I try to compile the project, it reports error (12006): node instance "nios_bts_port_core_i" instantiates undefined entity "nios_bts_port_core". Has anyone had such problem before?

Thanks,

Leon.
