ID:126000 Node "<name>" is modified or duplicated by <algorithm> -- node is set to Always Allow

CAUSE: You turned on an optimization for the specified node and you set the Netlist Optimizations option to Always Allow, to always allow netlist optimizations for the node. If the optimization involved duplication, it is possible that the timing assignments for the original node were not assigned to the duplicated node due to the new node name, 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.
