Cyclone V - Differential Pair Pin Assignment 1.5V PCML fitter error

When creating a new Quartus project similar to a demo example, I am trying to place XCVR pins in a blank project and getting an error from the 1.5V PMCL differential pins (HSMC_GXB_RX_p0 and HSMC_GXB...

    Hi Terra,


    I have told you earlier, you cannot directly connect, Please design custom logic to reconstruct the word. First correct your design then try to compile.


    Thank you

My project is empty except for pin locations, which file extensions are what you want to see?

I am trying to figure out what is the minimum I need to connect the pins together.

My goal is just to make a straight through connection between these pins:


INPUT: HSMC_GXB_RX[0] on PIN_AD2 (HD-SDI in)

OUTPUT: HSMC_GXB_TX[0] on PIN_AE4 (HD-SDI out)


Any suggestions would be very helpful. I am using the Terasic Developement board C5G with an SDI mezzanine breakout board so I can't really move the pins around too much.

The signal that I am passing through is HD-SDI. (It is NOT a dual link)
