Verify

1b. DFA Verification (9 tests)

python3 scripts/verify_dfa.py

Tests include:

• BOM file presence and component counts
• CPL file presence and component positions
• Polarity-sensitive component verification

1c. Datasheet Physical Verification (29 tests)

python3 scripts/verify_datasheet.py

Cross-checks PCB component physical characteristics against datasheets:

• Pin count per component (ICs, connectors, passives, switches)
• Pad pitch (0.5mm, 1.27mm, 2.0mm etc.)
• Pad span / body dimensions (catches wrong package variants)
• NPTH positioning hole count and drill size
• THT drill sizes
• Datasheet PDF presence

2. Design Rule Check (JLCPCB rules)

python3 scripts/drc_check.py

Checks: trace width, via spacing, drill clearance, silkscreen width.

3. Electrical Connectivity

python3 scripts/test_pcb_connectivity.py

Verifies trace/pad/via graph connectivity for all nets.

4. Schematic-PCB Consistency

python3 scripts/verify_schematic_pcb.py

Checks footprint count, part values, net consistency between schematic and PCB.

5. Short Circuit Analysis (optional)

python3 scripts/short_circuit_analysis.py

Detects net connectivity conflicts and zone priority issues.
