Model Checking is Possible to Verify Large-scale Vehicle Distributed Application Systems

Abstract: OSEK/VDX is a specification for vehicle-mounted systems. Currently, the specification has been widely adopted by many automotive companies to develop a distributed vehicle application system. However, the ever increasing complexity of the developed distributed application system has created a challenge for exhaustively ensuring its reliability. Model checking as an exhaustive technique has been applied to verify OSEK/VDX distributed application systems to discover subtle errors. Unfortunately, it faces a poor scalability for practical systems because the verification models derived from such systems are highly complex. This paper presents an efficient approach that addresses this problem by reducing the complexity of the verification model such that model checking can easily complete the verification.
