ID:186174 Can't place input clock "<name>" at pin <name> that is in same quad as XGMII state machine "<name>" because input clock "<name>" will power down when <name> signal is asserted on XGMII state machine "<name>"

CAUSE: The Fitter cannot place the specified input clock at the specified pin location because the pin location is located in the same quad as the specified XGMII state machine. If the input clock is placed in this quad, it will power down when the specified signal is asserted on the XGMII state machine. This behavior is not supported in simulation.

ACTION: Assign the input clock to a pin location in a different quad.
