Model-based software development is increasingly being used to develop software for electronic control units (ECUs). When developing safety-related software, compared to non-safety-related software development, additional requirements specified by relevant safety-standards have to be met. Meeting these requirements should also be considered to be best practices for non-safety-related software. This paper introduces a model-based reference workflow for the development of safety-related software conforming to relevant safety-standards such as IEC 61508 and ISO 26262. The reference workflow discusses requirements traceability aspects, software architecture considerations that help to support modular development and ease the verification of model parts and the code generated from those model parts, and the selection and enforcement of modeling and coding guidelines.
