wavedrom-cli

WaveDrom command-line interface for converting digital timing diagrams defined in JSON5/JS object notation into SVG or PNG images. Current stable version is 3.2.0, requiring Node.js >=12 (recommended v14+). It supports rendering signal groupings and outputs SVG natively; PNG export uses the native SVG renderer. Unmaintained for some time (last significant release v0.3.x), with breaking changes from prior versions that relied on PhantomJS. Key differentiator: enables programmatic and CI-based generation of timing diagrams without a browser.
