ID:170145 Incremental routing to signal "<name>" NOT successful

CAUSE: You either started Signal Probe routing, or specified a number of Signal Tap incremental routing connections. However, the Fitter could not successfully route the specified signal incrementally. A Programmer Object File (.pof) was generated; however, the specified incremental connection is not included in the POF.

ACTION: For a Signal Probe compilation, assign the specified Signal Probe pin to a different pin, or use the allow modification of previous fitting results option. For Signal Tap incremental routing, use a different Signal Tap input, though it may not be possible to route this signal incrementally.
