ID:186132 I/O pin "<name>" placed at pin "<name>" powers down when the pllenable signal is de-asserted on XGMII state machine atom "<name>"
CAUSE: The specified I/O pin is powered down when the pllenable
signal is de-asserted on the specified XGMII state machine
atom. This behavior is not supported in simulation and is allowed because you turned on the corresponding logic option.
ACTION: No action is required. To avoid receiving this message in the future, modify the design to remove the pllenable
signal.
