Wave dumping with `LogicArray`s and `LogicStructure`s #384

Closed mkorbel1 closed 11 months ago

mkorbel1 commented 1 year ago

Motivation

375 introduced LogicArrays and LogicStructures, but did not test or consider the WaveDumper. There are likely some modifications necessary, and definitely some tests required.

Desired solution

Write tests for the WaveDumper considering different scenarios of LogicArray and LogicStructure and implement necessary upgrades to make everything work right.

Alternatives considered

Will work on this!

The example below shows the VCD file generated for a test with LogicArray

VCD currently does not support LogicArray representation (https://github.com/verilator/verilator/issues/3167) and therefore, we can close this issue for now. An alternate solution would be to split the bus by arrays, however, that would create numerous waves and it would be hard to view them unless there is a search option in the Wave Viewer.

Thanks for looking into all this @mjayasim9! Yes, we can close this for now since VCD doesn't seem to have any nice support for arrays anyways.
