The Power Constraint Advisor reports the tool-computed switching activity on all control signals in the design and is sorted starting with highest fanout. Review this list for Low confidence levels, which indicate resets with high switching activity and enables with very low or zero switching activity. Both factors contribute to erroneously optimistic power results. For more information, see Power Constraints Advisor in the Vivado Design Suite User Guide: Power Analysis and Optimization (UG907).
