A Model-Based Reference Workflow for the Development of Safety-Critical Software

International audienceModel-based software development is increasingly being used to develop software for electronic control units (ECUs). The automatic conversion of models into program code for ECUs plays a major role in this because it ensures efficientimplementation, providing considerable savings potential and short development cycles. This paper introduces a model-based reference workflow for the development of safety-critical software conforming to relevant safety-standards such as IEC 61508 and ISO 26262. The reference workflow provides guidance for meeting the safety requirements to develop software up to and including SIL 3 and/or ASIL D. Furthermore the paper shows how such a reference workflow can help address the issue of software tool qualification
