7 years agoI am pretty sure it is because you are not using dedicated PLL output pins. What device are you and which one of the PLLs are you using?
I am also looking for help on how to SDC constraints for soft LVDS RX and TX, but find very little on that subject. None of the example project with soft LVDS has any SDC constraints on it!
