EDA DRC Skill
Design validation, rule checking, and pre-manufacturing review.
Auto-Activation Triggers
This skill activates when:
- User asks to "check design", "validate", "run DRC"
- User asks about design errors or warnings
- User mentions manufacturing readiness
- Project is approaching completion
- User asks "is this ready for fabrication?"
Context Requirements
Requires:
hardware/*.kicad_sch - Schematic fileshardware/*.kicad_pcb - PCB layoutdocs/design-constraints.json - Project constraintsdocs/component-selections.md - Selected components
Produces:
docs/validation-report.md - Comprehensive validation report
Validation Scopes
/eda-check schematic
- Run ERC (Electrical Rules Check)
- Verify power connections
- Check decoupling capacitors
- Validate against datasheet requirements
- Check component values
/eda-check pcb
- Run DRC (Design Rules Check)
- Verify placement guidelines
- Check routing rules
- Validate copper pours
- Review silkscreen
/eda-check components
- Verify stock availability on LCSC
- Check current pricing
- Identify lifecycle issues
- Suggest alternatives if needed
/eda-check manufacturing
- Generate and review Gerbers
- Verify BOM completeness
- Check position file accuracy
- Validate against manufacturer specs
/eda-check full
- Run all above checks
- Comprehensive pre-manufacturing validation
Workflow
1. Load Context
@docs/design-constraints.json
@docs/component-selections.md
@docs/schematic-status.md
@docs/pcb-status.md
2. Run Automated Checks
- Execute DRC/ERC via KiCad MCP
- Capture all violations and warnings
3. Manual Review Checklist
Use reference documents to verify:
- Common issues are addressed
- Manufacturer constraints are met
- Design guidelines followed
4. Component Verification
For each selected component:
- Check LCSC stock status
- Verify pricing
- Check for lifecycle warnings
5. Generate Report
Create comprehensive validation report documenting:
- Pass/fail status for each check
- List of issues found
- Recommended actions
- Sign-off status

Guidelines
- Run DRC frequently during layout, not just at the end
- Address all errors before manufacturing
- Document intentional rule violations
- Verify component availability before finalizing design
- Keep validation report updated as issues are fixed

reference/COMMON-ISSUES.md - Frequent problems and solutionsreference/MANUFACTURER-SPECS.md - Manufacturer capabilitiesreference/VALIDATION-CHECKLIST.md - Pre-manufacturing checklist
Next Steps
After validation passes:
- Run
/eda-export [format] to generate manufacturing files
- Update
design-constraints.json stage to "complete"
