ID:176203 Differential I/O standard <name> cannot be used on the <name> pin <name>

CAUSE: You assigned the specified differential I/O standard to the specified pin, but the I/O standard cannot be used by the specified pin.

ACTION: Assign an I/O standard that can be used by the specified pin. In some cases where you can't use a true differential I/O standard, it is possible to use a pseudo-differential IO-standard (for example, LVDS_E_3R) with LVDS termination.
