ID:176173 Can't place node "<name>" with differential I/O <name> in location (<number>,<number>,<number>) -- location does not support differential pin pair functionality

CAUSE: The Fitter tried to place the specified node with the specified differential I/O standard in the specified location. However, the location does not exist in the target device. As a result, the Fitter could not place the node. This error can occur if you changed the location assignment for the node with the differential I/O standard.

ACTION: Modify the design so that the location assignment of the node is a legal location.
