adom-ds2sf

Datasheet → symbol + footprint + provenance. Read a chip's PDF, extract its pins and pads, and emit structured JSON the rest of the Adom EDA tools build on.

adom-ds2sf ("datasheet to symbol & footprint") reads a manufacturer datasheet PDF and extracts the part's electrical interface — pin names, numbers, types, and logical groups (POWER, GROUND, GPIO split by port, DEBUG…) — plus the land pattern when the datasheet provides one, into <MPN>-symbol.extracted.json and <MPN>-footprint.extracted.json with per-field provenance: every pin and every dimension records the datasheet page it came from. It's the source that lets adom-symbol auto-generate a clean, balanced, grouped symbol straight from the datasheet — independent of any vendor's CAD draw.

What it does

• extract — datasheet PDF → symbol + footprint + provenance JSON.
• inspect — summarize an existing extraction in a chip directory.
• svg — regenerate the authoritative footprint SVG from cached JSON (no re-extraction).

Note: a datasheet without a land-pattern table yields a symbol but no footprint pads — adom-ds2sf reports exactly what it could and couldn't extract, with provenance on every datapoint.

Seven worked examples

Each example below was produced by adom-ds2sf extract on the manufacturer's own datasheet. For every part you can see the generated symbol + footprint, the full extracted pin list, the provenance JSON (with the datasheet page each datapoint came from), and the actual datasheet pages adom-ds2sf read — plus a link to the original PDF. Seven different part types, seven different packages.

Open source — check it out, vibe-code it, send it back

adom-ds2sf is MIT and fully open. The complete Rust source is in this page's Files tab.

1. Build it. cargo build --release drops a standalone binary.
2. Point your install at your checkout. adompkg link john/adom-ds2sf ./adom-ds2sf.
3. Vibe-code a change. Open it in Claude Code — a new provenance field, a different grouping heuristic, another datasheet quirk to handle.
4. Send it back. Open a pull request on this page, or start a discussion thread.

Part of the Adom EDA family

adom-ds2sf is the extractor; its results are viewed and used through adom-symbol / adom-footprint (it has no viewer of its own). It feeds adom-chip-fetcher's source carat as the "adom-ds2sf · datasheet" source.

Run it

adom-ds2sf extract <chip-dir>     # datasheet PDF → symbol + footprint + provenance JSON
adom-ds2sf inspect <chip-dir>     # summarize an extraction

MIT, contributions welcome.

Contributing & forking — open source under the Adom org

adom-ds2sf is open source under the adom org on the Adom Wiki. The full source lives in this page's repo — open the Files tab, or adompkg install adom/adom-ds2sf and edit the package. Third-party developers are welcome to modify it and contribute back.

Modify it

• Get the source from the Files tab (or adompkg install adom/adom-ds2sf), make your changes, and rebuild.

Contribute back to Adom — two paths

1. Pull request (preferred). The wiki runs a PR-per-page flow: propose your change on this page and the maintainer reviews + merges it — no fork needed.

2. Fork + breadcrumb. Prefer your own fork or add-on? Publish it as your own wiki page, then drop a breadcrumb on this page pointing at your fork so it's discoverable:

   • Read existing trails: GET https://wiki.adom.inc/api/v1/pages/adom-ds2sf/breadcrumbs
   • Attach a breadcrumb from your fork's page targeting this anchor (a short label + your slug).

   The breadcrumb leaves a linked path back here, so Adom's AI can auto-discover your fork and surface it to users — the trail is followable both ways. Your fork stays yours; the original stays discoverable.
