The DLT Analyzer is a software tool designed to collect and analyze log and trace information from a vehicle ECU. The tool works in the Eclipse environment in order to facilitate the integration with other ECU software development suite. It is available both as an Eclipse plug-in or as a stand-alone application.

The tool is useful in the following phases of the ECU software life cycle:

  • Development: the DLT Analyzer helps the designer to tune and control the implemented SW vehicle functionalities, managing in an effective way the logging and tracing of variables and parameters. It permits the developer to prepare the log information to be used in the after production phase.

  • After production: the DLT Analyzer permits the developer to elaborate the log information, that are useful to identify and solve software problems generated during the vehicle running.

  • The DLT Analyzer presupposes that the ECU basic software includes the Diagnostic Log and Trace module standardized by the Autosar Consortium and available from the official release 4.0, or the DLT Daemon from the GENIVI Consortium.

Main Functionalities:

  • Communication: communication with ECU can be performed using different physical interfaces. Supported interfaces are TCP/IP and RS 232; CAN interface is under development and will be soon available.

  • Configuration: the DLT Analyzer permits the operator to modify at runtime the logging capabilities of the applications registered with the embedded DLT module It also permits to configure the whole DLT target module behaviour.

  • Filtering: the operator can apply filters criteria in order to manage only the subset of log and trace data of interest. All filters are applied using enhanced indexing techniques, in order to reduce seek time on huge data files.

  • Acquisition: the tool is able to acquire log and trace data produced by the applications running on the ECU and to save them into file on the host machine. The DLT Analyzer supports verbose mode and non-verbose mode in a transparent way to the user. Non-verbose mode files can be managed using the Intecs FIBEX Editor plug-in.

  • Data Analysis: the operator can access a database of ‘dlt’ file saved during previous acquisition sessions and process them. The Analyzer is able to process up to 10GB of data in less then an hour. The analysis capabilities will be increasable thanks to an extensible architecture. Graphical analysis tools are provided inside the plug-in itself.

  • User Interface: the DLT Analyzer usability get advantage of the Eclipse environment.
