0.1.2 - 2026-06-26¶

Placement & routing building blocks: create_cell, use_cell, place_cell (instance or array), add_via (cut array + enclosing metal), and add_wire (Manhattan, auto L-corners). Drawing tools now target a switchable active cell.
klayout-pnr skill with recipes — row placement, power rails, and an obstacle-aware maze (Lee) router — plus an end-to-end place-and-route demo.
Documentation: Installation, Getting Started, Placement & Routing, an auto-generated Tool Reference, and a run_script cookbook — with rendered screenshots, a DRC violation visualisation, and a layer colour legend.

load_gds(path, top_cell?) — load an existing GDS/OASIS file into the session for editing.
inspect_gds(path?) — per-layer shape count, merged area and bbox, plus the cell list, for a file or the current session.
drc_check(rules, path?) — simple DRC: spacing, width, overlap, separation and enclosure rules, reporting violation counts and locations.
Documentation page covering the editing and DRC workflow.

Initial MCP server with drawing tools: new_layout, add_box, add_polygon, add_path, add_label, layout_info, save_gds, open_layout, open_editor, and the run_script escape hatch for the full klayout.db API.
Example gallery: basic shapes, NMOS transistor, CMOS inverter, and a 1 µm 4T CIS APS pixel tiled as a 2×2 array, with headless screenshot rendering.
