Cyclone V - PCIe p and n signals reversed

[SVN_21]

Hi,

We are using Cyclone V SoC device(5CSTFD5D) for PCIe application and realized that p and n lines of all tx and rx got reversed on PCIe connector that connects to PC. Can we reverse the signals in verilog assignments or is there any other method to invert the signals at PCIe hip instantiation.

Thanks.
