1.3.4.1. Clock Node Toggle Rates

For clock nodes, the Power Analyzer uses timing requirements to derive the toggle rate when neither simulation data nor user-entered signal activity data is available. fMAX requirements specify full cycles per second, but each cycle represents a rising transition and a falling transition. For example, a clock fMAX requirement of 100 MHz corresponds to 200 million transitions per second for the clock node.
