trace.xplorer

The trace.xplorer enables a very detailed and interactive analysis of recorded measurement data, which can include numerical signals and bus messages as well as video and audio streams. Signals can be viewed, formatted and compared with other signals at high performance. Events can be marked in the trace and time spans or signal amplitudes can be measured.

Each Trace analysis generates a Test report with detailed analysis results when it is executed. The static information contained in this report can be exploratively understood using trace.xplorer. This allows conclusions to be drawn on questions such as:

  • Should the trace analysis (or even the test case) be corrected, made more robust, or extended?

  • How exactly did the present evaluation of the system under test (SUT) come about?

  • How good is the quality of the recorded signal data (measurement resolution, dropouts, outliers, …)?

  • Does automated testing of ECUs require additional signal data to be recorded?

Variants and differences

In ecu.test, interactive visualization of signal data and test case evaluations is done by default with trace.xplorer basic. If its range of functions is not sufficient, trace.xplorer can help with advanced evaluation of the result data. It requires an extra license and offers additional features compared to the basic variant, for example:

  • importing, exporting and printing of signal data

  • deleting unneeded signal data from existing documents

  • fast event search using simple, logical signal conditions

  • script-based signal analysis for more complex problems

  • time shifting of signals

  • creating and deleting signal groups

  • configuring additional Wireshark capture interfaces (see extcap.exe)

While trace.xplorer basic can only display ASTRACE files, trace.xplorer supports the following data formats with its import/export interfaces:

  • ASTRACE, AS3TRACE

  • CSV, MDF4, PCAP, PCAPNG, ASC, BLF, TTL

  • MP4, MKV, AVI, ASF

Configuration

The default program for viewing traces can be changed in the Included programs section of the local ecu.test settings.
