Changelog¶

1.0.0 - 2026-04-27¶

First stable release. Marks API parity with the upstream Magic Tcl pcell generators and a stable public surface for downstream tools.

Breaking¶

• Major refactor: ported electrical pcells from Magic Tcl generators with XOR-validated parity (#157)
• Replaces the legacy per-device pcell modules (nmos.py, nmos_5v.py, pmos.py, mimcap_1.py, mimcap_2.py, …) with consolidated modules under sky130/pcells/ (mosfets.py, bjts.py, capacitors.py, diodes.py, esd.py, guard_ring.py, contact.py).
• Adds sky130.logic and sky130.fixed cell collections.
• Removes legacy top-level sky130/nmos.py shim that shadowed sky130.pcells.nmos (#174).
• Bumps minimum Python to >=3.12.
• Routing + port mapping rework for gdsfactory+ integration (#135, #151).

New¶

• @cell type tags on all components (#170).
• DRC workflow + numeric DRC badge (#154, #169).
• Metric badge workflows + README dashboard (#168).
• Magic-batch reference generator + parameter sweeps for XOR test infrastructure (scripts/magic/).

Fixes¶

• build_cell.py: port all_cells aggregator from IHP template; restore green DRC (#174).
• sky130/circuits/sample.pic.yml: switch routing to route_bundle (#174).
• Docs build, pre-commit, dependency resolution (#155).
• Hide private repo links from public docs (#153).

Maintenance¶

• Sync drift-enforced workflow templates from upstream (pages.yml, dependabot.yml, release-drafter.yml, test_code.yml, issue.yml, claude-pr-review.yml) (#172, #173).
• Switch dependabot to uv ecosystem with cooldown (#156, #163).
• Bump gdsfactory to ~=9.40.1 (#166).
• Bump release-drafter/release-drafter 6 → 7.1.1 (#159).
• Bump actions/deploy-pages 4 → 5 (#161).
• Revert "Migrate CI to centralised pdk-ci-workflow" (#150).
