ModelSim DO File Grouping is a Visual Studio Code extension for cleaning up and reorganizing ModelSim/QuestaSim waveform .do files. It helps you make large wave setups easier to read by grouping signals into a clear structure, then lets you review and export the processed result from an interactive custom editor.
Features

Automatically groups signals based on their hierarchy path (default behavior)
Optional name-based grouping is available, and it groups signals whose names share at least 4 leading characters
