Aligning Hardware EBOM and Embedded Firmware Software BOM
A smart automotive Tier 1 supplier producing Advanced Driver Assistance System (ADAS) domain controllers integrating radar sensors, cameras, and microcontrollers.
Run on Sama · Traceability & Product Data
The challenge
Hardware engineering teams revised PCB components and microcontroller chip revisions without synchronized updates to the Software BOM (SwBOM).
Embedded firmware builds compiled for older microcontroller silicon steppings failed during vehicle flash programming at assembly plants.
Software and hardware revision mismatches caused vehicle functional test failures, delaying factory gate releases by up to 12 days.
How Sama solves it
Hardware to Software BOM Cross Domain Linking
Sama binds hardware part numbers, PCB layout revisions, and silicon stepping registers directly to embedded firmware build versions.
Silicon Stepping & Driver Compatibility Validation
Automatically validates firmware driver compatibility whenever an electronic component part revision is released in the EBOM.
Automated Flash Image Dependency Checking
Ensures the correct bootloader and application binaries are mapped to specific microcontroller silicon revisions in the MBOM.
Digital Twin Configuration Auditing
Maintains an auditable digital twin mapping every physical controller serial number to its certified firmware binary hash.
Manufacturing Flash Station Synchronization
Dispatches validated hardware software pairing rules directly to factory line flashing stations.
The outcome
- elimination of hardware silicon and firmware build flashing
- 0%elimination of hardware silicon and firmware build flashing
- end of line vehicle electrical validation failure rate reduced
- 0%end of line vehicle electrical validation failure rate reduced
100% elimination of hardware silicon and firmware build flashing mismatches on the factory floor.
End of line vehicle electrical validation failure rate reduced from 8.5% to 0.1%.
Accelerated ECU variant introduction lead time by 3 weeks per program launch.

Capabilities used
Every accelerator is assembled from the same capability layer, so a workflow you adopt here shares its foundation with the rest of the portfolio.
