Sample013-sdi mipi video converter

dataset-srj24

Simple Route JSON dataset generated from 26 production-oriented KiCad and Altium boards. The first 20 sources are pinned to immutable Git commits, redistributed under Apache-2.0, and retained byte-for-byte in kicad_pcb/. The six Texas Instruments Altium sources are pinned by SHA-256 to official TI design-resource archives; their PcbDoc files are not redistributed here.

The selection excludes testbeds, simulation boards, ICT fixtures, archived projects, and repositories described upstream as experimental. The designs are complete hardware projects intended for their documented functional use. This dataset validates source integrity and conversion, but it is not an independent electrical-safety or manufacturing certification.

Repository structure

• kicad_pcb/ contains the exact upstream KiCad boards.
• circuit-json/ contains converter output for each board.
• samples/ contains Simple Route JSON with existing top-level routing removed.
• snapshots/ contains labeled, side-by-side original Altium, converted Circuit JSON, and SRJ SVGs for the TI samples.
• source-files.json records immutable provenance, license links, descriptions, features, statistics, converter warnings, compatibility normalizations, and any unambiguous missing-port repairs.
• src/ and index.html provide the same local viewer structure as dataset-srj18.

Compatibility normalization is applied only to the in-memory conversion input. It removes unsupported graphic UUIDs or routing-state fields that do not affect the unrouted SRJ problem. Missing PCB ports are repaired only when a connected source port has exactly one pad or plated-hole candidate with the matching pin hint. The checked-in .kicad_pcb files are never rewritten.

Licensing

Original code and documentation in this repository are licensed under the MIT License unless otherwise stated. The unmodified boards in kicad_pcb/ and their generated board data remain under Apache-2.0. The TI-derived Circuit JSON, SRJ, and comparison snapshots are subject to the applicable TI Terms of Use; the native PcbDoc files are downloaded only during regeneration and are not redistributed by this repository. The repository-level MIT license does not relicense third-party materials. The full policy is in LICENSE, the Apache-2.0 text is in LICENSES/Apache-2.0.txt, and immutable source attribution is in THIRD_PARTY_NOTICES.md and source-files.json. None of the pinned upstream revisions contains a root NOTICE file.

Usage

const { sample001, dataset } = require("@tscircuit/dataset-srj24")

Regenerate and validate

bun install
bun run generate
bun run test
bun run build

The generators download each pinned source, verify its commit or SHA-256, convert it to Circuit JSON, and then produce Simple Route JSON. The TI samples store the released Altium converter and SRJ output without repairing or normalizing it; the comparison SVGs make the resulting conversion limitations visible.

The TI samples (021–026) preserve the Circuit JSON board's via-in-pad policy as allowViaInPad, defaulting to false when the source policy is unspecified. Validation rejects a missing or mismatched policy in these samples. The public type keeps this field optional because the older KiCad samples omit it.
