An ISO 26262 compliant design flow and tool for automotive multicore systems

Abstract

The complex interactions between suppliers and OEMs as well as between suppliers in the automotive industry make it necessary to clearly define processes and models for the exchange of information between different companies. Especially when several suppliers are jointly working on the same product, reducing friction and adhering to common standards are a necessity. In addition, standards like AUTOSAR and ISO 26262 put additional requirements on the processes and tools.In this paper, we report on our efforts to standardise the design flow and the modelling environment for automotive suppliers. In particular, we analyse the existing design flows at the suppliers, as well as the current state of an advanced automotive modelling tool, the Amalthea platform. Furthermore, we analyse compliance of both the design flows and the platform with the ISO 26262 standard, identifying which aspects of the standard are already covered and which are currently missing. From this, we derive recommendations and a roadmap to achieve full coverage of the standard with the aim of providing a single integrated platform with an accompanying design methodology
