Activity Profiler

The Activity Profiler tool converts SEGGER SystemView binary trace files (.SVDat) into a JSON file following the Catapult format. The resulting file can be visualized in two viewers:

• Chromium DevTools: the Performance tab of any Chromium-based browser (default format).

• Perfetto: Google’s trace visualization tool at https://ui.perfetto.dev/.

A trace loaded in the Chromium DevTools Performance tab.

This provides a graphical, time-correlated view of OS scheduling, UI rendering, and application behavior on the embedded target, complementing the Event Tracing system and the SystemView integration in the VEE Port.
