Output file

Write out signal activities used during power analysis

Directs the Power Analyzer to create a Signal Activity File (.saf) Definition, which records the toggle rates and static probabilities that occur during power analysis. If you select this option, you must specify a file name in the Output file name box.

Turning on this option is useful when you are using a large Value Change Dump File (.vcd) Definition from a third-party simulator. You can record signal activities to a .saf file during the initial running of the Power Analyzer, and then use this .saf file as input to subsequent power analyses, thereby saving the time required to reread a large .vcd file.

Output file name

Allows you to specify the path and name of the .saf file that records the toggle rates and static probabilities that occur during power analysis. If you do not specify a path, the Power Analyzer creates the resulting file in the project directory.
