Power report and analysis windows are integrated into the Vivado® Integrated Design Environment workspace as shown in the following figure. These windows enable navigation across the different power views and cross probing to the existing view.

  • The Power settings section displays all the device, tool, and environment settings used with power calculations.
  • The Summary section displays a concise view of the most important thermal and supply power results.

Navigate through your design by type of resources with the Utilization Details section or Netlist view to review configuration, utilization, and activity details for the selected elements in the Statistics tab of the Properties window. You can generate multiple reports to estimate power under different operating conditions or different activity patterns. Some of the values in the Utilization Details views (for example, Frequency in the Clocks view or Signal Rate in the I/O view) are color coded as shown in the following figure to indicate the source of the value used by Report Power to perform the power analysis. A legend at the bottom of the window indicates the source specified by each color (for example, the value was supplied by a Simulation activity file, or was User Defined, or a Default value was assigned by the vectorless propagation engine).

Important: Report Power supports Zynq®-7000 SoC and Zynq® UltraScale+™ MPSoC power analysis on Zynq-7000/ Zynq® UltraScale+™ MPSoC blocks configured through the IP integrator. You configure the PS usage and functionality through the IP integrator. Report Power estimates power based on these configuration settings. The power estimate within Vivado® is read-only; you cannot edit the Signal Rate or Static Probability of the PS specific processor, interfaces or memory at this time. For more details on the individual fields in the PS tab of Xilinx® Power Estimator, refer to the PS Sheet section in the Xilinx Power Estimator User Guide (UG440).
Important: Report Power supports power estimation of VCU (Video Codec Unit) for Zynq UltraScale+ EV devices. VCU is configured through the IP integrator for resolution, color format and other properties. Report Power estimates power based on these configuration settings. For more details, refer to the Other Sheet section in the Xilinx Power Estimator User Guide (UG440).
