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 generated by simulation of the gate-level design netlist, by supported third-party simulators
  • 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.
