You can add a virtual bus to your wave configuration, which is a grouping to which you can add logic scalars and arrays. The virtual bus displays a bus waveform, which shows the signal waveforms in the vertical order that they appear under the virtual bus, flattened to a one-dimensional array. You can change or remove virtual buses after adding them.
To add a virtual bus:
- In a wave configuration, select one or more signals or buses you want to add to a virtual bus.
- Select , or right-click and select New Virtual
Bus from the pop-up menu.
The virtual bus is represented with the Virtual Bus button
.The change is visual and nothing is added to the HDL code.
You can move other signals or buses to the virtual bus by dragging and dropping the signal or bus name. The new virtual bus and its nested signals or buses are saved when you save the wave configuration file. You can also move it to another location in the waveform by dragging and dropping the virtual bus name.
You can rename a virtual bus; see Renaming Objects.
To remove a virtual bus, and ungroup its contents, highlight the virtual bus, and select , or right-click and select Ungroup from the pop-up menu.
