20.2.11 Power Options

Enables you to set options that affect the graphical and textual reports. To open the SmartPower Power Options dialog box:

• From the File menu, select Options.
• Select the Options panel in the Power Report dialog box.
• Click the icon in the SmartPower toolbar.

  

There are two sections: Units and Use Toggle Rates.

• Units: Sets unit preferences for power (W, mW, W) and frequency (Hz, KHz, MHz).
  • Use Toggle Rates: When toggle rates are active (Use Toggle Rates box is 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 enable 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.
