Bosch Builds System Architectural Design of ECUs According to Automotive SPICE

Interfaces are automatically created inside the Simulink elements, and if we describe external interfaces in these Simulink models, they appear in the static architecture. It is really helpful to have a toolchain that is automatically ensuring consistency.


Bosch is the world’s largest independent supplier of automotive parts, including ECUs, and faces a volume of projects, each with significant design variance.

To streamline Automotive SPICE compliant ECU design, the Bosch Powertrain Solutions team needed a toolchain that would support the SYS.3 System Architectural Design Process and that customer accounts would readily accept.

With the Simulink family of products, Bosch created an integrated design environment. They use System Composer™ to automatically build system architectures, including interfaces and requirements links through database import. They manage allocation, traceability, and consistency of requirements with Requirements Toolbox™.

The system enables them to evaluate design alternatives and transfer models across projects. They generate reports on the architecture linked to requirements and reference models.

Using this platform, Bosch has successfully passed an Automotive SPICE assessment and measured high user acceptance at customer accounts.

Key Outcomes

  • High user acceptance at customer accounts
  • Scalability to project volume through reuse of reference models
  • Individual design architectures realized through automated import and model creation
