The power graph in the Timeline window is available from the C-SPY driver menu during a debug session.

The power graph displays a graphical view of power measurement samples generated by the debug probe or associated hardware in relation to a common time axis.

Note

There is a limit on the number of saved logs. When this limit is exceeded, the oldest entries in the buffer are erased.

Display area

Where:

  • The label area at the left end of the graph displays the name of the measurement channel.

  • The graph itself shows power measurement samples generated by the debug probe or associated hardware.

  • The graph can be displayed as a thin line between consecutive logs, as a rectangle for every log (optionally color-filled), or as columns.

  • The resolution of the graph can be changed. Note that if you change the setting to a very coarse resolution ("zooming out"), the same point in the graph can come to represent two or more values. In that case two values will be shown for that point on the X axis. The darker one is the lowest value for that point and the lighter one is the highest value for that point.

  • A red vertical line indicates overflow, which means that the communication channel failed to transmit all interrupt logs from the target system.

At the bottom of the window, there is a common time axis that uses seconds as the time unit.
