15 years agoI went through the Wizard pages of the PCIe IP and the PCIe transceiver settings for both Hard and Soft implementation and it does not look like you can reverse the polarity. The usual switches are greyed out. I know polarity inversion is supported in other protocols (I am currently doing that with an Arria II GX, but with the transceivers running in Basic mode.) MySupport would have a more accurate answer though. Sometimes they have switches that are not in the Wizard GUI.
