Pin-to-net mapping auditor -- verifies that every IC pin in the schematic is connected to the correct net, matched against a pin map source of truth (CSV, datasheet table, or Python dict). Critical for BGA/QFN devices where swap errors are invisible to DRC/ERC.

ERC and DRC cannot catch a swapped pin. A power pin on a signal net passes all automated checks but produces a dead or damaged board. The only defense is comparing the schematic pin-to-net assignment against the datasheet pinout table.

exists.Unmapped pins should get no-connect markers rather than floating unconnected. Floating digital inputs can cause latch-up or undefined behavior.
Flag any IC below 80% mapped. No-connect pins count as mapped.

SOT-23 transistors: BCE, BEC, EBC, and CBE orderings all exist for NPN BJTs;
GDS, GSD, SGD for N-MOSFETs. The KiCad symbol lib_id suffix encodes an assumed
pinout. Verify against the actual MPN's datasheet -- especially when no MPN is set.
Multi-unit ICs: Op-amp and gate packages with a shared VCC/GND unit. Ensure the power unit is placed and connected -- a missing power unit causes an ERC warning that can be overlooked.
Active-low signals: Verify RESET_N, CS_N, OE_N are driven with the correct polarity. A high-true signal on an active-low input means always-asserted.

Route non-critical nets on a real KiCad PCB or Specctra DSN through Circuit Weaver's fail-closed Freerouting integration. Use after placement and net-class setup when the user requests autorouting, a validated SES session, routing diagnostics, or post-route cleanup. Keep critical power, RF, clock, crystal, switching, and differential nets manual.

Manage an electronics bill of materials across distributors and fabricators: part selection, stock, pricing, alternates, ordering, KiCad properties, and BOM/CPL export. Use for distributor-neutral sourcing, cost comparison, order preparation, or requests such as "what parts do I need" and "export for JLCPCB". Do not take over schematic analysis or a complete new-design workflow unless the requested task is specifically its sourcing/manufacturing stage.

Create, import, analyze, resume, or revise an end-to-end Circuit Weaver electronic design from requirements through validated functional KiCad schematics, placement review, and a truthful manufacturing handoff. Use for new designs and for existing KiCad/PCB/Gerber projects that need durable state. Use kicad for one-off file inspection, bom for standalone sourcing, and design-wizard only when the user explicitly requests the slower questionnaire.
