ID:126011 Node "<name>" is modified or duplicated by <algorithm> -- node directly drives a global signal

CAUSE: You turned on an optimization for the specified node. If the optimization involved duplication, it is possible that due to the limited number of global signals, the duplicated node may not be routed to a global signal, which may affect the timing of the design.

ACTION: If the timing for the design is satisfactory, no action is required. Otherwise, turn off the option that resulted in the optimization of the specified node.
