Visualizing Bit Field Diagrams

Hover a SystemVerilog packed struct or union type inside the editor to visualize the bit field diagram.

The members are represented from left to right, from most to least significant.

Differentiating Member Types

In order to differentiate member types, check the legend located at the top.

For additional information, such as type or position, check the table below the diagram.

Nested Bit Field Diagrams

For each member of a packed struct or union type, the bit field diagram of its own type is also presented below the member.

Each union member is represented on a separate lane.

Diagram Tools and Controls

The diagram's view controls and its ability to be maximized make it more convenient than tooltips for exploration of larger diagrams.

Use the toolbar button to save the diagram to a file.
