ID:176654 Cannot place memory interface I/O group in any legal location

CAUSE: The Fitter could not place the specified I/O group 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.
