Abstract

We present a solution to the Generalized Railroad Crossing benchmark problem based on the ESTEREL programming language. The solution is shown to satisfy the formal statements of the properties that the system requirements specify by using a verification method for safety properties of ESTEREL programs recently developed. The solution and verification presented have been developed within the synchronous system model, i.e. discrete time, global broadcast of events and instantaneous reactions.
