ID:21752 Signal <Name of signal> will not be considered for automatic promotion to the global clock network because it is placed at a non-dedicated clock pin location.

CAUSE: The source signal is locked to, or was placed in, a pin that is not a dedicated clock pin (ie. the pin has no direct connectivity to the global network).

ACTION: To allow the signal to be considered for automatic promotion, place the source in a dedicated clock pin. To manually promote the signal, use a GLOBAL_SIGNAL QSF assignment.
