Ensuring high quality in specifications for automotive embedded control systems

Abstract

Achieving confidence in safety, and robustness of complex systems is a key issue for an automotive manufacturer. Specifications are the first and crucial stage of the engineering process. The aim is to provide a high level of quality assurance for the specifications of systems incorporing several reused parts. This paper presents a method using an external modeling of the function supervision. We propose a framework based on modes analysis and a formal operation which allows to combine automaton descriptions of modes by adding logic commutations between modes.
