Enabling Scheduling Analysis for AUTOSAR Systems

Abstract

AUTOSAR (Automotive Open System Architecture) is enjoying increasing interest and broad acceptance in the automotive domain. AUTOSAR aims at defining an open standardized software architecture to face future challenges in automotive development including the development of time-critical systems (e.g. brake-by-wire or steer-by-wire). Mastering the development of such systems requires being able to analyze their real-time behavior. Scheduling analysis is the theory that studies how far a real-time system may satisfy its real-time requirements against its real-time properties. In this paper, we will study to what extent it is possible to apply some of those scheduling analysis techniques on real-time systems deployed on AUTOSAR-compliant architectures. The paper focuses on scheduling analysis techniques implemented in one open source tool. A concrete case study shows the feasibility of the approach and shows scheduling analysis results.
