MadakeCAD

MadakeCAD is an AI-first electrical CAD for industrial equipment, built for JIS, IEC and ISO compliance. It draws standards-compliant wiring diagrams for robots, machinery and control panels, with an AI assistant that edits through the same undoable command engine as the user, and verification grounded in a real circuit solver (ngspice). It is in alpha, and the README reports 1,737 spec clauses tested.

The editor ships 47 bundled JIS C 0617 and IEC 60617 symbols plus parametric terminal blocks, connectors and PLC modules, orthogonal wiring with grid and pin snap, auto reference designators, multi-sheet drawings, reusable circuit macros, coil to contact cross-references and PLC I/O assignment tables with generated ladder pages. A 2D panel layout sheet covers enclosures, DIN rails and ducts, footprints sized from the parts database, and overlap, off-rail and rail-fill checks. Output is standards-true: a JIS drawing frame today, print-quality SVG and PDF, and seven reports (from-to wire list, terminal chart, terminal connection diagram, BOM, cross-reference, PLC I/O and panel layout table).

Verification is solver-grounded: ERC plus electrical checks (reachability, ampacity, voltage drop, fuse rating) judged from an actual ngspice DC solution, plus DC simulation with net voltages, component currents and power, and open-switch what-if analysis. The AI assistant drafts and edits the drawing via MCP, knows the JIS and IEC drafting conventions, and verifies its own work (ERC, fix, re-verify) before reporting back; every AI turn is undoable. Six providers are offered: Claude Code CLI, Anthropic API, GitHub Copilot CLI, any OpenAI-compatible endpoint, a local Ollama, or Google Gemini. An MCP server, REST API with SSE and a madake CLI drive the same command engine.
