DLT Viewer

DLT Viewer is a log inspection tool from COVESA for the Diagnostic Log and Trace format. DLT is the standardised logging and tracing protocol used on automotive electronic control units, where messages are tagged with an ECU identifier plus application and context identifiers and carry a binary payload rather than plain lines of text. A viewer for this format decodes those messages into readable records and lets an engineer narrow a long trace down to the component under investigation.

The program is aimed at people reading traces captured from a target device or streamed from it during a test run: bring-up work, integration debugging and post-mortem analysis of a recorded session. Because DLT files are binary and often large, tooling of this kind is the practical entry point to them; a general text editor will not resolve the framing or the identifier tables.

This listing covers a Linux build. The license is MPL-2.0, a file-level copyleft that permits use inside larger projects while keeping modifications to the covered files under the same license. Which DLT protocol revisions, plugins and connection types the build supports is not stated in the facts given here.
