ID:176495 Can't place <name> I/O pin "<name>" at location <name>

CAUSE: The Fitter cannot place the specified DQS I/O, nDQS or DQ I/O pin at the specified location. The location may have been chosen by the Fitter due to location assignments. If you did not make the location assignment, the specified location represents the last location in which the Fitter attempted to place the specified I/O pin.

ACTION: ACTION = If you made a location assignment to the DQS I/O, nDQS, or DQ I/O pin, remove the assignment if possible. If you did not make a location assignment, modify the location assignments of the other I/O pins in the design. If this does not result in a successful fit, compile the design targeting a larger device.
