Integrated tool-chain for improving traceability during the development of automotive systems

Tool integration is a key factor for improving development efficiency and product quality during the development of safety-relevant embedded systems. We present in this work a demonstrator based on the most recent outcomes of the CESAR project. The proposed integrated tool-chain aims at better linking development activities together, thus improving traceability during requirements engineering, system design, safety analysis and V&V activities using a model-based development approach. We analyze the proposed tool-chain from three different points of view: (1) tool integrator, (2) technology provider, and (3) end-user. These different points of view enable the description of the different technologies used at the different levels and the analysis of the benefits for the end-user.
