Using the SystemView (Segger) reader

Content outdated

We are in the process of migrating all content to impulse version 2.0.

SEGGER's SystemView environment is a real-time recording and visualization tool that visualizes the runtime behavior of embedded applications. With the new SystemView serializer, you can use impulse to read and analyze SystemView recording data from files or directly from running targets.

Screen Cast: Using the SystemView reader

Using eclipse/impulse as backend for SystemView, you may

  • read SystemView data from different sources or paths (e.g. tcp, serial line,..),
  • read SystemView data from multiple cores in parallel,
  • combine multiple source and formats(e.g: additional traces or logic analyzer data),
  • automatically analyze the input data using scripts,
  • extract custom statistical data,
  • use additional presentation forms like charts, line and area diagrams,
  • filter and search for specific events,
  • add annotations (bookmarks,..) and deploy to customers or colleagues.


The SystemView reader can be used to open resources (*.SVDat) and together with ports (direct connection to the target using TCP, Serial, J-Link, ...).

Target configuration

For information about how to instrument and use SystemView on the target refer to

Please be aware that the reader has no back-path when using with a running target (ports). This means that you need to start the SystemView process manually with SEGGER_SYSVIEW_Start().



You can modify the serializer behavior under Preferences->impuse->Serializer->[serializer name]:
  • You may modify the serializer parameters (see "Parameters" - global variables depending on the serializer type).
  • You may add serializer configurations. You can select one configuration when using the serializer.
The SystemView reader requires a serializer configuration to work. Get to Preferences>impuse->Serializer->SystemView, press Add and select the SystemView configuration:

The configuration requires a domain base to be set (this is ns by default) and optionally a list of user/rtos events. This list uses the same format as in SystemView (you may copy the content of the files SYSVIEW_embOS.txt or SYSVIEW_FreeRTOS.txt into this field). You may define multiple configurations for multiple targets.

View templates

After opening the viewer you will be asked to add a new view (you may create multiple views and switch between of them). A view describes all graphical presentations and can be created and modified by the user.

Chose the template "SystemView Default View" to create a ready-to-use view. You may later extend and modify the view according to your needs.
