Integrating Safety Design Artifacts into System Development Models Using SafeDeML

Applying a safety artifact language as Safety Design Modeling Language SafeDeML integrates the generation of the safety design into the system modeling stage – directly within the system architecture. In this paper, we present a modeling process and a prototype for the CASE tool Enterprise Architect for SafeDeML. The goal is to support the system designer in developing a standard (in this paper Iso 26262) conform system and safety design containing all relevant safety artifact within one model. Such integration offers several modeling guarantees like consistency checks or computation of coverage and fault metrics. Since all relevant information and artifacts are contained within the model, SafeDeML and the prototype can help to decrease the effect of structural faults during the safety design and further supports the safety assessment. To give an idea to the reader of the complexity of the approach’s application, we present an exemplary implementation of the safety design for a brake light system, a real case-study from the Iso 26262 context.
