power report

The power report command is used subsequent to the power add command. Data produced by these commands can be translated (by a Synopsys utility) to drive the Synopsys power analysis tools. This command writes out the power information for the specified signals or nets. The report can be written to a file or to the Main window. Returns nothing.

Syntax

power report

[-all] [-noheader] [-file <filename>]

Arguments

-all

Writes information on all items logged. Optional.

-noheader

Suppresses the header to aid in post processing. Optional.

-file <filename>

Specifies a filename for the power report. Optional. Default is to write the report to the Main window.

Description

The report format for each line is:

signal path, toggle count, hazard count, time at a 1, time at a 0, time at an X 
  • toggle count is the number of 0->1 and 1->0 transitions
  • hazard count is the number of 0/1->X, and X->0/1 transitions

Note that if a signal is initialized at X, and later transitions to 0 or 1, it is not counted as a hazard.

You will also need to know the total simulation time.
