Viewing Energy Analysis Data with Intel® VTune™ Amplifier

Note

Collecting energy analysis data with Intel® SoC Watch is available for target Android*, Windows*, or Linux* devices and provided only with the Intel System Studio. Import and viewing of the Intel SoC Watch results is supported with any version of the VTune Amplifier.

After you collect energy analysis data on your target system, using the Intel® SoC Watch collector, you can import a result file (*.pwr) to Intel® VTune™ Amplifier on your host system, and view Platform Power analysis data with the following windows. The windows that appear depend on which metrics are collected:

Viewing Component Rows in the Timeline Pane

Some rows can expand and reveal component rows. Look for an arrow next to the row name, as in the timeline shown below.


Zoom in on a Specific Section in the Timeline

Click and drag horizontally across the rows to select a time interval within the total collection. Release the mouse button to see a list of options for zooming in on this interval. Zoom In and Filter In by Selection is particularly useful because it will not only zoom, but also recalculate all of the grid’s summary data based on the current selection. Once a filter has been applied in one tab it will persist across all tabs within that viewpoint, highlighting the selected time interval on each tab. Right-click and select Remove All Filters to restore the original grid and clear the selection from the timeline.
