1.3.2. Specifying 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 activity data from the following sources:

  • .vcd files from supported simulators
  • User-entered node, entity, clock, and toggle rate assignments
  • Vectorless estimation (selected devices)

You can mix and match the signal activity data sources on a signal-by-signal basis.
