Hi,

I think the number of available pins in that bank are less than your requirement. As per the IO pinout sheet, bank 3C has 24 pairs of LVDS pins. Your requirement is 28 + one more pair for IOPLL. This is not possible. Check the pinout file and place the pins accordingly.


Regards

Even if I try to assign only two instances of LVDS serdes, It generates the error.

The only working scenario is one iopll assignment and one lvds serdes assignment.
