Separating Control and Data Flow: Methodology and Automotive System Case Study

摘要

In this document we propose to study the control/data flow separation design methodology, using Scade and Mode-Automata, and its application in the design of an automotive system. This methodology allows to facilitate the specification of different kinds of systems and to have a better readability. It also separates the study of the different parts by using the most appropriate existing tools for each of them. To do that, we study a cruise control system with GPS which makes possible the control of a car speed depending on its position given by a GPS. This system combines both control and data processing and can be specified using our methodology. The goal of this work consists in presenting the application of our methodology on a real system and studing its advantages notably for formal verification.
