CAUSE: You turned on an optimization for the specified node. If the optimization involved duplication, it is possible that the original and duplicated nodes may have different values, which can cause changes to 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.
