Default toggle rate used for remaining signals

Allows you to specify a default toggle rate for the Power Analyzer to assume for all non-input signals.

  • Use default value—Directs the Power Analyzer to assume a default toggle rate that you specify. You can specify the toggle rate as a percentage, or as a number of transitions per second.
Note:

The Power Analyzer assumes a static probability of 0.5 for all unspecified signals.
