2.2. 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.
- You can customize the generated Power and Thermal Calculator export file name. This file summarizes the resource utilization and allows you to perform what-if analyses in PTC
- 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.
