GTKWave is a nice tool for displaying signal traces, while developing with Hardware Description Languages, and has many formatting features like changing signal color, grouping signals in a hierarchy, etc. However, it can become tedious to manually edit through the GUI. Also, its document format, while ASCII, is a bit cryptic, and contains extra information pertaining to the GUI (window and panel sizes, last modification date, etc.), making it inconvenient for placing in revision control.
A Domain Specific Language for generating GTKWave documents was developed, separating signal description and structure from style, not unlike HTML+CSS, but described using Python Lists and Dictionaries. This makes it especially suitable for embedding in Python-based Hardware Description Languages and Simulators.
While it fits my own needs, I'm hopping to gather some feedback on this tiny library, so it could be made more generally useful.
