3. **Placement Optimization** - Thermal-aware component positioning
4. **Automated Routing** - FreeRouting integration with optimization
5. **Design Validation** - DRC checking and compliance verification
6. **Manufacturing Prep** - Gerber, drill, and assembly file generation
7. **Final Analysis** - Quality scoring and recommendations

### Real-time Capabilities
- Live board statistics and connectivity monitoring
- Interactive component placement and routing
- Real-time design quality scoring
- Live optimization opportunity identification

## Usage Examples

```python
# Complete project automation
automate_complete_design("/path/to/project.kicad_pro", "rf",
                        ["signal_integrity", "thermal"])

# Automated routing with strategy selection
route_pcb_automatically("/path/to/project.kicad_pro", "aggressive")

# Real-time board analysis
analyze_board_real_time("/path/to/project.kicad_pro")

# Outlet tester project creation
create_outlet_tester_complete("/path/to/new_project.kicad_pro",
                             "gfci", ["voltage_display", "gfci_test"])
```

This update establishes the foundation for Claude Code to provide complete
EDA project automation, from initial design through production-ready
manufacturing files, with real-time KiCad integration and automated routing.
