In the Report Power dialog box, click OK to start the power analysis. The tool does the following.
  1. Takes into account the environment, device, and tool options.
  2. Reads the netlist connectivity and configuration.
  3. Applies activity factors for the nodes you defined.

    A node is a component such as a net, pin, or port.

  4. Determines activity for any remaining undefined nodes before computing the thermal and supply power.

Power analysis uses different sources of information for activity definition, including:

  • Simulation files (SAIF)
  • Automatic calculations using a vectorless power analysis methodology
  • Manual definition using the set_switching_activity Tcl command

For more information, see Running Power Analysis from the Tcl Prompt.
