ID:176318 I/O assignment analysis allows pin "<name>" assigned to dedicated GXB transmitter output pin location <name> (<name>) to not be fed by the dataout output port of a GXB transmitter. However, pin "<name>" must be fed by the dataout output port of a GXB transmitter for Fitter to run successfully.

CAUSE: You ran the Fitter with the specified pin assigned to the specified gigabit transceiver block (GXB) transmitter output pin location. However, the specified pin is not fed by the dataout output port of a GXB transmitter. The I/O assignment analysis flow continues to run, but this error causes fitting to fail. The specified pin must be fed by the dataout output port of a GXB transmitter.

ACTION: Remove the pin assignment, or feed the pin from the dataout output port of a GXB transmitter.
