KiCadRoutingTools

Analyzes a KiCad PCB file and creates a comprehensive routing plan. Examines components for fanout needs (BGA/QFN/QFP/PGA), identifies differential pairs, categorizes power/ground nets, and presents a step-by-step routing workflow with explanations.

Stress-tests the router against real-world open-source KiCad boards (downloaded, normalized, stripped of routing), measuring routing completion rates and DRC violations per board. Aggregates results and files GitHub issues for new router/parser findings after user approval. Use to regression-test the router at scale or to hunt for robustness issues.

Identifies differential pairs on a KiCad PCB by pin function via datasheet lookup, catching pairs whose net names don't follow P/N conventions. Recommends per-interface routing parameters (differential impedance, gap, intra-pair matching) and outputs ready-to-use route_diff.py commands.

Post-route QA on a KiCad board. Runs the DRC, connectivity, and orphan-stub checkers, verifies length/time-match groups landed within tolerance, checks GND return via coverage on high-speed nets, and reviews differential pairs. Produces a pass/fail sign-off report with concrete next actions. Works on boards routed by this tool, by hand, or by other tools.

Analyzes a KiCad PCB to identify high-speed and impedance-controlled nets by looking up component datasheets via AI. Classifies nets by speed tier (ultra-high/high/medium/low), detects RF/antenna feeds and other controlled-impedance nets, estimates max frequencies and rise times per interface, and recommends GND return via distances AND impedance-controlled routing: target ohms, the route.py/route_diff.py --impedance commands, and near-fab-floor width/spacing (~0.1 mm gap & clearance, impedance-derived width clamped to the floor) that override and update the board's Default net class.

Root-causes failed routes from a routing run's logs and the board file. Parses the JSON summary, failed-net histories, and blocking reports, correlates failures spatially with board regions and components, classifies the failure mode, and outputs a ready-to-run retry command. Use after route.py/route_diff.py runs report failed nets.

Recommends net -> plane-layer assignments for a KiCad PCB with signal-integrity rationale. Reads the stackup, identifies plane-worthy nets (GND plus power rails by pad count and current), and assigns copper layers (GND adjacency for return paths, GND/VCC pairing for interplane capacitance, split layers for multiple rails). Use before creating planes on the Planes tab or with route_planes.py.

Reviews a KiCad board's stackup and recommends a fab-realistic one. Flags untouched default stackups, validates that target impedances are achievable with manufacturable widths using the project's own IPC-2141 formulas, and outputs the routing arguments (--impedance, plane layers) that follow. Use before impedance-controlled routing or time matching.

Analyzes KiCad PCB files to identify power nets by looking up component datasheets via AI. Use when you need to determine which nets are power/ground nets and what track widths to use, especially when KiCad pintype annotations are missing or unreliable.
