1.3. Power Analyzer Walkthrough

The Intel® Quartus® Prime Power Analyzer requires post-fit design.

You must either provide timing assignments for all clocks in the design, or generate activity data from a simulation-based flow. 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. From the Intel® Quartus® Prime Software, open the Power Analyzer tool by clicking Processing > Power Analyzer Tool.
  2. If you have signal activity information for the project, turn on Use input files to initialize toggle rates and static probabilities during power analysis, and then click Add Power Input Files to specify input files.
    For more information about generating those input files, refer to Sources for Signal Activity Data.
  3. To direct the Power Analyzer to write a Signal Activity (.saf) output file, turn on Write out signal activities used during power analysis, and specify the file name.
  4. 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.

    With this file, you can import design information into the Early Power Estimator spreadsheet, and perform what-if analyses.

  5. Specify the default toggle rate for input I/O signals.
    The Power Analyzer uses the default toggle rate when no other method specifies the signal-activity data.
  6. Specify the default toggle rate for the remaining (non input) signals.
  7. Define the cooling solution and temperature.
  8. Click Start.
