ID:176149 SERDES transmitter <name> must drive one output pin

CAUSE: The Fitter tried to place the specified SERDES transmitter. However, the specified SERDES transmitter does not drive a true differential output pin. The SERDES transmitter must drive one true LVDS output pin.

ACTION: Modify your design to ensure that the SERDES transmitter drives only one true LVDS output pin. Alternatively, you can implement the SERDES transmitter in LE mode, which allows you to drive I/O standards other than true LVDS.
