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

Frequent ContributorHi,
Few question for you.
Q1. What are you feeding to TX as an input, there must be some initial value?
Q2. If there is how are you feeding it?
Even though you feed some constant value to the transmit, there is higher probability you will see the bit shift at the receiver. You need to reconstruct the word or design a word aligner in the FPGA fabric.
On top of everything, you should not try in this way of looping back.
Thank you
