ai-generated-autorouter-for-kicad

An advanced autorouter for KiCAD PCB design, featuring AI-assisted routing and strict adherence to design rules.

Features

• A Maze Routing*: Efficient pathfinding with support for 45° and 90° routing.
• Design Rule Compliance: Reads track width, clearance, and via constraints directly from the board's settings and net classes.
• Copper Zone Awareness: Skips connections already completed by copper zones.
• Multi-layer Support: Handles 2-layer and multi-layer (4, 6, ...) boards.
• Two-phase Routing: Attempts via-free routing first, then uses vias only when necessary.
• Rip-up and Reroute: AI-guided rip-up and reroute with configurable attempt budgets.
• Persistent Settings: Router cost settings are saved to ~/.kicad_autorouter_settings.json.
• AI Advisor: Integrates with Claude API for optimal routing order and rip-up suggestions.

Quick Start

Scripting Console

import sys; sys.path.insert(0, '/path/to/kicad_autorouter')
from autorouter import KiCADAutorouter 
routed, failed, total = KiCADAutorouter().run_rur()

With AI Guidance

from ai_advisor import RouteAdvisor
from autorouter import KiCADAutorouter

router = KiCADAutorouter()
routed, failed, total = router.run_rur(advisor=RouteAdvisor(), max_attempts=100)

Note:

• Requires pcbnew (KiCAD scripting).
• For AI features, install anthropic (pip install anthropic) and set the ANTHROPIC_API_KEY environment variable.
