CAUSE: A pseudo-differential output pin exists without its complement pin. Moreover, a differential buffer is used and the output enable of the buffer is in use. The Fitter will not split this differential buffer to create a complement pin path because the driver of the output enable of the complement buffer is unknown and the Fitter cannot duplicate the entire output enable path.
ACTION: Fix the design by either creating a complement pin for the pseudo-differential pin or using a true differential I/O standard.
