WaveDrom Timing Diagrams
WaveDrom is a tool that draws timing diagrams (waveforms) from a simple textual description written in JSON. DVT renders WaveDrom waveforms in the Inspect View. The waveform diagram is updated on the fly (as you type).
The waveform description can be:
either embedded in comments, surrounded by @WAVEDROM_START…@WAVEDROM_END pragmas
or in files with *.json or *.json5 extensions
When the waveform description is found in a file with a valid extension, the Inspect View will process it’s content and render the diagram when opened. The waveform description file can also be embedded in comments using the @WAVEDROM_FILE pragma, followed by its location. The location of the file will be solved relatively to the project root.
To save the diagram as an SVG file, right-click on it in the Inspect View.
DVT offers the ability to view WaveDrom diagrams through tooltips, by hovering over any waveform written inside DVT editors.
Tip
The WaveDrom documentation is available here.
Note
To specify additional file extensions, use the +dvt_wavedrom_file_ext_add+<extension> build config directive. To clear the extensions list use +dvt_wavedrom_file_ext_clear.
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 extensions list use +dvt_wavedrom_files_location_clear.
Note
By default, only waveform descriptions of maximum 5000 characters are rendered. You can change this threshold from menu Window > Preferences then DVT > Editors.
Note
DVT uses WaveDrom version 3.5.0.

Trace Connections View
The Trace Connections View presents a hierarchy similar with the Design Hierarchy View:
The connected instances are displayed, the rest are filtered out.
You can use Show Root and Show Full Hierarchy options to show the entire design. The connected instances are colored, the rest are grayed-out.
Port icons indicate the direction of the signal.
Sources and destinations are marked with red/green decorations.
You can search for a specific connected instance or signal with Quick Search in Views.
The toolbar buttons allow you to change the trace kind:
Trace Drive and Load shows the connected instances across the drive and load paths (how is this signal connected in the design)?
Trace Drive shows the connected instances across the drive paths (who drives this port?).
Trace Load shows the connected instances across the load paths (who does this port drive?).
Other buttons:
Show Root shows the path to the hierarchy root, even if the signal doesn’t reach it. It provides the enclosing context for deep traces, for example when tracing a signal many levels below the top module. This option is enabled by default.
Show Full Hierarchy shows the full hierarchy, whether it is reached by the traced signal or not (how is this signal connected in the whole design context?).
Show As List to view only the sources and destinations as a list.- Show/Hide Signals shows or hides the ports or internal signals of the currently selected instance.
Show Diagram to view a graphical representation of signal traces.
At any time you can see the traced signal (the port or internal signal you are currently tracing). It is indicated in the info label. The two connected instances that are bold colored in the tree represent:
The instance with the traced signal.
The instance with the signal shown in the trace path. More details Trace Path.
Double-click on an element to go to code:
