3.6.4.2 EnergyTrace Within a Debug Session
When a debug session is launched, the core is connected, and the EnergyTrace tool is started, three
EnergyTrace windows appear. The windows include the EnergyTrace Technology (main view), which
shows the statistical data, the Power graph, and the Energy graph. Trace collection starts when the core
runs and stops, either when the core halts or when the stopwatch timer in the main view expires,
depending on whichever occurs first. The trace collection time can be changed by clicking on the
stopwatch icon in the EnergyTrace Technology window.
Figure 8 shows a sample collection of 10 seconds. The Main UI shows the average, minimum, and
maximum current and power consumed, as well as the total energy consumption. It also indicates the
estimated battery life. The graphs show the consumption over time.
Figure 8. EnergyTrace Overview
The EnergyTrace session is automatically terminated when the debug session is terminated. To terminate
EnergyTrace collection while debugging, click on the red power icon in the EnergyTrace Technology
window.
3.6.4.3 EnergyTrace Without Debug Intervention
In this capture mode, true energy measurements can be performed without debug overhead. To do so,
first disconnect the JTAG header from the target. To start the tool, click on the blue icon with the
EnergyTrace Logo from the CCS Toolbar, as shown in
Figure 9 .
