Before PCB layout

Review a KiCad schematic with AI—and verify the evidence

Use structured project analysis to catch omissions and questionable assumptions, then confirm every finding with KiCad checks, datasheets, measurements, and engineering judgment.

An AI schematic review is most valuable as a second set of eyes. It can scan more context than a hurried manual pass and explain why something deserves attention. It is least reliable when it receives only a screenshot or when its claims are not tied back to exact symbols, pins, nets, footprints, and datasheet limits.

The KiCad schematic review checklist

  1. Establish the design intent. Record input conditions, rails, loads, interfaces, expected environment, and what failure would mean.
  2. Inspect the power tree. Check regulator limits, current budget, sequencing, protection, decoupling, grounding, and every power pin.
  3. Check component pin use. Compare pin names, electrical types, alternate functions, no-connects, and required biasing against primary datasheets.
  4. Review interfaces. Verify voltage compatibility, pull-ups, termination, level shifting, ESD protection, polarity, and connector pinouts.
  5. Confirm support circuitry. Look for reset, boot, clock, programming, reference, compensation, filtering, and thermal requirements.
  6. Validate symbols and footprints. Confirm package variants, exposed pads, pin numbering, orientation, and symbol-to-footprint mapping.
  7. Plan for test and manufacturing. Add accessible power, ground, clock, bus, reset, and programming test points; ensure all BOM entries are orderable.
  8. Run native checks. Use KiCad ERC, inspect every exception, and carry approved findings into PCB DRC and fabrication review.

What to give an AI reviewer

Provide the native KiCad project or a structured export when possible, plus requirements, BOM, datasheets for critical parts, and known exceptions. A rendered PDF can help explain layout, but it loses machine-readable connectivity and metadata. Screenshots alone are the weakest input.

What a useful finding looks like

Weak: “The power supply may be unstable.”

Useful: “U3’s feedback divider produces a nominal value outside the stated 3.3 V rail tolerance; verify R12/R13 against the regulator equation on the cited datasheet page.”

A review finding should identify the exact component or net, explain the rule or source behind the concern, state confidence, and recommend a verification step. Circuit Weaver preserves component provenance and produces validation evidence so findings remain connected to project state.

AI review does not replace ERC, DRC, or a design review

KiCad ERC checks formal electrical rules. AI-assisted analysis can add contextual questions that ERC does not understand. Human review handles architecture, risk, ambiguous datasheets, layout tradeoffs, and safety. Use all three layers together.

High-risk areas requiring specialist review

Mains voltage, batteries with high fault energy, isolation barriers, medical or automotive safety functions, RF, high-speed memory, precision analog, unusual power sequencing, and high-current thermal design should never be cleared solely by an AI report.
