Model-based Methodology for Requirements Traceability in Embedded Systems

We present a model-based methodology for requirements traceability proposed in the framework of the MeMVaTEx project. The methodology relies on the EAST-ADL language and the two UML 2.0 profiles: MARTE for real-time embedded systems, and SysML for system requirements modeling. Along the paper, we illustrate the proposed methodology by an automotive case study, namely a knock controller, focusing on the time aspects of the requirements specified with the MARTE UML 2.0 profile. We explain how to define the requirements according to a proposed classification, and we present the tracing mechanisms based on the SysML UML 2.0 profile. Finally, we describe the proposed MeMVaTEx methodology which extends the EAST-ADL methodology in order to take into consideration the expression of requirements, and their traceability along the life cycle.
