dsh-svw-waveform

Waveform files are the single most important debugging artifact in digital verification, yet AI-assisted analysis often stops at plain text, forcing engineers to switch back to Verdi or GTKWave by hand. dsh-svw-waveform embeds native SVW waveform rendering directly into DeepSeek Harness: the model supplies a VCD or FST path, a tick range, and up to twelve hierarchical signal names, and the Web UI immediately presents an interactive viewer with zoom, pan, edge navigation, radix switching, and delta-cycle markers. On surfaces without the client plugin, it gracefully falls back to a full ANSI terminal waveform card so the result is always readable.

Beyond one-off rendering, the plugin ships a bundled svw-waveform skill that guides the agent through the entire workflow-from signal discovery and value/change tracking to waveform comparison, semantic-design review, UVM debugging, and coverage closure. Binaries are pinned to SVW GitHub Releases with SHA256 verification and platform-isolated packaging, so a replaced asset produces a new immutable patch rather than silently overwriting a version. Current support covers Linux x64 and macOS arm64.

If you work in ASIC or FPGA verification, UVM methodology, or digital front-end design and lean on AI to help pinpoint timing or protocol issues, this plugin removes the friction of jumping between a chat window and a waveform tool, keeping waveform analysis inside the conversation where it belongs.
