Specify VCD file, Tb Turn On Time Based Reporting

Command Line Options

-s (Specify VCD file)

-s [simdata.vcd]

Sets activity rates and signal frequencies using data from the VCD file. If no file is specified, XPower searches for an input design file with a .vcd extension.

-tb (Turn On Time Based Reporting)

-tb [number][unit]

Turns on time-based reporting. Must be used with the -s option. XPower generates a file with a .txt extension. The specified number and unit control the time base of how often the total power is reported. For example, if 10ps is selected, XPower reports the total instantaneous power every 10 picoseconds of the simulation run. If the simulation runtime for the VCD is 100ps, XPower returns 10 results.

Units are:

ps = picoseconds

ns = nanoseconds

fs = femtoseconds

us = microseconds

-v (Verbose Report)

-v [-a]

Specifies a verbose (detailed) power report. Use of the -a argument specifies an advanced report. See “Power Reports” below for more information.

-wx (Write XML File)

-wx [userdata.xml]

Writes out an XML settings file that contains all of the settings information from the current XPower run. If no filename is specified, the output filename is the input design filename with a .xml extension.

-x (Specify Settings (XML) Input File)

-x [userdata.xml]

Instructs XPower to use an existing XML settings file to set the frequencies of signals and other values. If an XML file is not specified, XPower searches for a file with the input design filename and a .xml extension.
