B.25. recalculate_power

Usage

recalculate_power [-h] [-help] [-long_help] [<auto|manual|get>]
Arguments
-h: Quick usage.
-help: Short help.
-long_help: Long help with examples and possible return values.
<auto|manual|get>: Enable or disable auto-recalculation, or query the mode.

Tcl Package and Version

Belongs to ::quartus::pta 1.0 .

Description

This command is used to control whether or not the power model is automatically updated when the design is modified. It can also be used to query the current state of automatic recalculation.

If no argument is specified, this command triggers recalculation of the power model.

Example Usage

recalculate_power
    recalculate_power auto
    recalculate_power manual
    recalculate_power get

Return Value

Code Name Code String Return
TCL_OK 0 INFO: Operation successful
