DVT can render bitfield diagrams from UVM register configurations in tooltips and in the Inspect View.

Trigger the tooltip from the Editor, by hovering a register class (a class that extends from uvm_reg) or a field of register class type:

To see the diagram in the Inspect View, simply click on a register class in the editor, UVM Browser View or UVM Sequence Tree View:

Tip: To save the diagram as an SVG file, right-click on it in the Inspect View.

Note: Depending on the length of the reg field names, diagrams are drawn in a horizontal or vertical layout. By default the layout selection is done automatically.

Tip: To force a specific layout go to menu Window > Preferences then Diagrams > Bitfield Diagrams.

Note: Diagrams are rendered using the WaveDrom BitField library.
