1.4.2. Sources for Signal Activity Data

The accuracy of the power estimation depends on how representative signal-activity data is during power analysis. The Power Analyzer allows you to specify signal activities from the following sources:

  • Simulation results
  • User-entered node, entity, and clock assignments
  • User-entered default toggle rate assignment
  • Vectorless estimation (selected devices)

You can mix and match the signal-activity data sources on a signal-by-signal basis. The following figure shows the priority scheme applied to each signal.
