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:
- To specify device power characteristics, operating voltage, and temperature conditions for power analysis, click Assignments > Settings > Operating Settings and Conditions, as Settings for Power Analysis describes.
- To run full compilation of your design, click Processing > Start Compilation.
- Click Assignments > Settings > Power Analyzer .
- Specify the source of signal activity data, as Generating Signal Activity Data for Power Analysis describes.
- To generate a Signal Activity (.saf) file during analysis, turn on Write out signal activities used during power analysis, and specify the file name.
- 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.
- Specify the Default toggle rates for unspecified signals, as Specifying the Default Toggle Rate describes.
- To specify temperature range and cooling options, click Cooling Solution and Temperature.
- To run full compilation of your design, click Processing > Start > Start Power Analyzer .
- When power analysis is complete, click Report to open the Power Analyzer reports that Viewing Power Analysis Reports describes.
