Chapter 10: XPower

Command Line Examples

The following command produces a standard report, mydesign.pwr, in which the VCD file specifies the activity rates and frequencies of signals. The output loading has not been changed; all outputs assume the default loading of 10pF. The design is for FPGAs.

xpwr mydesign.ncd mydesign.pcf -s timesim.vcd

The following command does all of the above and generates a settings file called mysettings.xml. The settings file contains all of the information from the VCD file.

xpwr mydesign.ncd mydesign.pcf -s timesim.vcd -wx mysettings.xml

The following command does all of the above and generates a detailed (verbose) report instead of a standard report. The verbose report is limited to 100 lines.

xpwr mydesign.ncd mydesign.pcf -v -l 100 -s timesim.vcd -wx mysettings.xml

Power Reports

This section explains what you can expect to see in a power report. Power reports have a

.pwr extension.

There are three types of power reports:

•“Standard Reports” (the default)

•“Detailed Reports” (the report generated when you run the “-v (Verbose Report)” command line option)

•“Advanced Reports”

Standard Reports

A standard report contains the following:

•A report header specifying:

♦The XPower version

♦A copyright message

♦Information about the design and associated files, including the design filename and any PCF and simulation files loaded

♦The data version of the information

•The Power Summary, which gives the power and current totals as well as other summary information.

•The Thermal Summary, which consists of:

♦Airflow

♦Estimated junction temperature

♦Ambient temperature

♦Case temperature

♦Theta J-A
