Description
Report power optimizations that have been performed on the design with the power_opt_design command.
Note: By default the report is written to the Tcl console or STD output. However, the results can also be written to a file or returned as a string if desired.
Arguments
-cell <args> - (Optional) Report power optimization for the specified cell or cell instances. By default, the power optimizations performed on the whole design are reported.
-file <arg> - (Optional) Write the report into a file. The specified file will be overwritten if one already exists.
Note: If the path is not specified as part of the file name, the file will be written into the current working directory, or the directory from which the tool was launched.
-format [ text | xml ] - (Optional) Specify the file format of the Power Optimization report when used with -file. The default file output is a text format file. The Vivado tool can also write an XML format file to allow for use by third party applications.
Note: When
-format xml is specified, the -append option is not supported.
-name <arg> - (Optional) The name to assign to the Power Optimization report when the command is run in GUI mode.
-append - (Optional) Append the output of the command to the specified file rather than overwriting it.
Note: The
-append option can only be used with the -file option, and is not compatible with the XML format.-return_string - (Optional) Directs the output to a Tcl string rather than to the standard output. The Tcl string can be captured by a variable definition and parsed or otherwise processed.
Note: This argument cannot be used with the
-file option.-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
Note: Message limits can be defined with the
set_msg_config command.Examples
The following example reports the power optimizations performed on the current design, writing them to the specified file in an XML format:
report_power_opt -format xml -file C:/Data/power_opt.xml
