Auto-Detection

Before running validation, discover existing projects in the current directory:

python -m circuit_weaver discover --json

If projects are found, use the detected paths for schematic and PCB files instead of asking the user for paths. Select the most recently modified project by default, or ask the user to choose if multiple projects exist.

For an unmanaged KiCad project, PCB, Gerber/drill directory, or ZIP, establish durable non-destructive state and run every applicable bundled analyzer:

circuit-weaver import-design "${SOURCE_PATH}" --analyze
circuit-weaver status "${PROJECT_ROOT}"

Review .circuit-weaver/analysis/index.json. Reuse valid cached evidence; run analyze-design "${PROJECT_ROOT}" --force only for an intentional rerun.

Audit Passes

Run all passes after any significant design change.

Pass 1: Spec vs Schematic

Verify every requirement in the design spec has a corresponding net or component.

• Power rails: all specified voltages present as named nets
• Required interfaces: USB, Ethernet, JTAG -- verify connector and IC present
• IO counts: verify pin counts match spec

Pass 2: Pin Map vs Schematic

For each programmatically mapped IC, verify the schematic matches the pin map.

circuit-weaver validate "${SPEC_PATH}" --enhanced --verbose

If the project has a separate pin-map source of truth, compare it with the schematic analysis explicitly. Do not invoke scripts/validate_pinmaps.py unless that project-specific script actually exists.

Critical checks:

• Power pins (VDD, GND, VDDIO) connected to correct rails
• Reset/enable pins asserted correctly
• Clock inputs connected to clock sources

Pass 3: Schematic vs BOM

Use the schematic analysis result registered in .circuit-weaver/analysis/index.json, then reconcile its references and footprints with assembly_manifest.json when the latter exists.

Every component must have: MPN specified, footprint matching the MPN package, DNP components flagged consistently.

Pass 4: Schematic vs PCB Layout

Use the registered PCB analysis result from .circuit-weaver/analysis/index.json. The static analyzer does not replace a real KiCad DRC run.

• Component count: schematic total minus DNP = PCB footprint count
• All schematic nets appear in PCB net list
• No unrouted nets

Pass 5: Datasheet vs Symbol

For each IC with an MPN:

1. Download datasheet (digikey skill)
2. Verify pin numbers/names match KiCad symbol
3. Verify footprint pad numbering matches package pinout

Running Validation

Quick (standard validation only)

python -m circuit_weaver validate design.yaml

Enhanced (with cross-reference audit, thermal, SI, power budget)

python -m circuit_weaver validate design.yaml --enhanced --verbose

Full audit with scoring

python -m circuit_weaver validate design.yaml --enhanced --detailed-score --verbose

Release-quality final schematic gate

circuit-weaver generate design.yaml --output output --require-kicad

Internal validation is not real KiCad verification. For a final generated design, require artifact_manifest.json to report kicad_verified: true and verification_status: verified. For imported native boards, run KiCad ERC/DRC on the actual project in addition to the bundled static analysis.
