Automating Firmware Generation from Schematics for Microcontroller based Designs

• github.com/DLR-RY/kicad_firmware_generation
• Group components to Groups → firmware interested in inter-Group connections
• Implemented for KiCad v9
• Applied in PCDU development process
• Found electrical design fault: swapped pins in PCDU

• 120 test cases
• Made with KiCad Open-Hardware projects
• Automatically add synthetic annotations to schematics
• Test runtime of kicad_firmware_generation
• Result: negligible runtime

• Inject faults into PCDU schematics:
  swap labels, delete cables
• 8885 unique faults
• Over a week on CES server
• Manual sample (300 cases) for fault classification
• Result: detected 75% of otherwise not found Group Pin swaps
