ID:176650 Cannot place <name> I/O "<name>" in any legal location

CAUSE: The Fitter cannot place the specified I/O in any legal location because of device constraints specified in the sub-messages.

ACTION: Refer to the sub-message(s) in the Message window to determine the device constraints. Reduce the complexity of the I/O standard, location, and other logic option settings. If this does not result in a successful fit, compile the design targeting a larger device.
