Kicad

This is a complete KiCad design review system that parses schematics, PCBs, Gerbers, and PDF reference designs into structured JSON you can reason about. It cross-references schematic to layout, traces nets, extracts BOMs, checks DRC/ERC, validates power trees and regulator circuits against datasheets, and runs EMC pre-compliance analysis. Every finding includes confidence labels and evidence sources. It enforces a real review contract: datasheet verification, SPICE simulation when available, thermal analysis, and explicit disclosure of what was skipped or could not be verified. Use it when you need more than a visual check before fabrication, or when you want to extract and validate circuits from manufacturer PDFs. It hands off to sourcing and fab skills once the design is vetted.
