14.3 Power Options

Allows you to set options that affect graphical and textual reports.

1. From the File menu, choose Options.
2. Select the Options panel in the Power Report dialog box.
3. Click the
   
   icon in the SmartPower toolbar.

   

   The dialog box has two sections: Units and Use Toggle Rates.

   • Units: sets unit preferences for power (W, mW, and uW) and frequency (Hz, KHz, and MHz).
   • Use toggle rates: when checked, the data frequency of all the clock domains is defined as a function of the clock frequency. This updates the data frequency automatically when you update the clock frequency. Toggle rates allow you to specify the data frequency as a percentage of clock frequency, but you can no longer specify the data frequency as a number, only as a percentage of the clock frequency. To specify data frequencies, clear the Use toggle rates option in the Preferences window.

   You can set the data frequency percentage when you create a new clock domain with toggle rates active. In addition, when toggle rates are active you can set the data frequency percentage in the Domain and Frequencies tabs.
