SAFARI_Presentation_Short_v1.ppt 3 / /P. Cuenot/ 2009.09.03 © Continental AG Goals Scope : Automotive electronics architecture (system + software + electronic hardware including Electrical Distribution System) Improve dependability including safety focus of automotive products (from vehicle to component) Ensure process compliance to ISO26262 at the best cost (automation required, and no over design) matching AUTOSAR requirements methods to reference supplier chain job split, liability and to respect Intellectual Property Early evaluation of safety architecture and reuse (quality and cost driven) Demonstrate preservation of functional design choice (safety oriented) on component architecture Improve and standardized interface within automotive supply chain Interconnected to others Automotive R&D projects including CESAR R&D initiative as multi-domain platform
SAFARI_Presentation_Short_v1.ppt 4 / /P. Cuenot/ 2009.09.03 © Continental AG SAFARI Vision Definition of application rules for functional safety process application (ISO26262) Based on ADL language and methods capturing Functional and Technical Design (e.g. EAST-ADL2/SySML) complementing AUTOSAR hardware introduction job split (responsibilities) of involved parties Providing Model Based Techniques for safety evaluation Automatic extraction and synthesis of failure mode Fault injection methods (target virtual hardware platform) Verification of functional design choice (safety oriented) into component implementation HW and SW COTS safety characterization (matching AUTOSAR syntax) Generative approach for code and test generation Early evaluation of architecture choice based on safety and multi-criteria metrics Mastering and enforcing reuse to reach details satisfying safety case documentation
