1.2. Running the Power Analyzer

Before running the Power Analyzer you must run full compilation of your design to generate the post-fit netlist. In addition, you must either provide timing assignments for all clocks in the design, or specify signal activity data for power analysis. You must specify the I/O standard on each device input and output, and the board trace model on each output in the design.

To run the Power Analyzer:

  1. To specify device power characteristics, operating voltage, and temperature conditions for power analysis, click Assignments > Settings > Operating Settings and Conditions, as Device Operating Condition Settings for Power Analysis describes.
  2. To run full compilation of your design, click Processing > Start Compilation.
  3. Click Processing > Power Analyzer Tool.
  4. Specify the source of signal activity data, as Generating Signal Activity Data for Power Analysis describes.
  5. To generate a Signal Activity (.saf) file during analysis, turn on Write out signal activities used during power analysis, and specify the file name.
  6. To direct the Power Analyzer to generate an Early Power Estimation file, turn on Write out Early Power Estimation file, and specify the file name. The Early Power Estimation file summarizes the resource utilization and allows you to perform what-if analyses in EPE.
  7. Specify the Default toggle rates for unspecified signals, as Specifying the Default Toggle Rate describes.
  8. To specify temperature range and cooling options, click Cooling Solution and Temperature.
  9. Click Start.
