16.3 WaveDrom Timing Diagrams

WaveDrom is a tool that draws timing diagrams (waveforms) from a simple textual description written in JSON.

The waveform description can be:

embedded in comments, surrounded by @WAVEDROM_START...@WAVEDROM_END pragmas
embedded in comments using the @WAVEDROM_FILE pragma, followed by its location (the location of the file will be solved relatively to the current editor)

To display a waveform diagram, you can:

hover over the description to see it in the tooltip
place the cursor on the description and use the "DVT: Show Diagram" command

Note: The WaveDrom documentation is available here.

Note: DVT uses WaveDrom version 2.6.8.

Note: To specify additional search file locations to use in junction with @WAVEDROM_FILE pragma, use the +dvt_wavedrom_files_location_add+<location> build config directive. To clear the locations list use +dvt_wavedrom_files_location_clear.
