ID:176134 Differential I/O node <name> assigned to pin <name>, but node must be assigned to pin <name> -- differential I/O node <name> is assigned to pin <name>

CAUSE: The Fitter tried to assign the first specified differential I/O node to the first specified pin. However, the first specified differential I/O node must be assigned to the second specified pin instead because the second specified differential I/O node is assigned to the third specified pin. As a result, the Fitter cannot assign the first specified differential I/O node to the first specified pin.

ACTION: Remove the location assignment for one of the specified differential I/O nodes, or modify the location assignment for one of the specified differential I/O nodes so that it does not conflict with the location assignment of the other specified differential I/O node.
