Report Power - 2021.2 English

Run the report_power command on an implemented design to ensure that the power constraints applied to the design reflect the initial power estimation and thermal design. The report_power command also shows any margin based on the constraints, ensuring design power is kept in check. When you are generating multiple runs to close timing, Xilinx recommends running report_power, because often the design with the most slack might not be the best from a power perspective. However, as long as there is slack, a design can be considered to have closed timing, and having the report power results for every run allows you to select the best implementation for power as well. For more information and an example script, see Xilinx Answer Record 76056.
