An Approach for Architectural Design of Automotive Systems using MARTE and SysML

Abstract

System architecture should describe the functions, services and constraints of the system under different and intelligible descriptions. In this research, strategies for architectural design are presented and analysed for Real-Time and Embedded Systems (RTES). More specifically, within this paper we present a convenient design model of an architecture for automotive systems through viewpoints of design. Models are considered at the operational, functional, logical and technical views of a system and they are able to represent, at early design descriptions, several functional and non-functional properties of RTES. The proposed approach is adopted in an industrial case study in the automotive domain. In addition to the viewpoints definition, this research presents a specific framework for RTES development. This strategy of design can highlight the properties of the RTES while describing the system in different abstraction levels. In addition, the strategy of research is qualitatively evaluated through interviews with experts of the domain in order to analyse if the viewpoints are representing the expected and desired system behavior.
