test-fixtures

Small, curated, redistributable EDA design files used as shared test fixtures by IntelligentElectron's tooling. This repo is public and meant to be cloned / submoduled by other repos' CI.

Who uses it

• universal-netlist — consumes this repo as a git submodule at test/fixtures for parser/connectivity tests (Altium + Cadence today; KiCad parser in development).
• pcb-lens — consumes this repo as a git submodule at test/fixtures; runs ipc2581/download-fixtures.sh to fetch the IPC-2581 boards for layout tests.

Layout

Dir	Contents
kicad/	10 KiCad projects, deliberately spanning flat → deep hierarchy, simple → complex, with buses / global & hierarchical labels / power symbols — chosen to exercise a KiCad parser.
altium/	Altium .PrjPcb / .SchDoc designs.
cadence/	Cadence Allegro / CIS designs (incl. exported .dat netlists).
ipc2581/	IPC-2581 PCB layout boards (RevA/B/C). Large XML downloaded on demand via ipc2581/download-fixtures.sh — not committed.
NOTICE.md	Upstream source, license, and copyright for every fixture.

The kicad/ set ranges from a single-sheet baseline (no hierarchy) up to 24-sheet, depth-5 hierarchical designs with hundreds of bus connections — so a parser that handles these handles the long tail.

Using it from another repo

git submodule add https://github.com/IntelligentElectron/test-fixtures test/fixtures
git submodule update --init --remote      # pull latest fixtures

In CI (actions/checkout), set submodules: true. The repo is public, so the default GITHUB_TOKEN can clone it — no extra credentials needed.

Licensing

Every fixture is open-source / open-hardware (permissive or OSHW licenses) and is redistributable with attribution; see NOTICE.md. If you are a copyright holder and want your files removed, please open an issue.
