From EAST-ADL to AUTOSAR Software Architecture: A Mapping Scheme

摘要

This paper addresses the gap between models describing system requirements, functions and architecture at a higher level of abstraction (such as SysML models), with respect to software/hardware architecture description (such as the AADL models) as the means to improve the development process or embedded systems. The EAST-ADL and AUTOSAR are the two focused architecture description formalisms in the presented work. While EAST-ADL is an architecture description language providing an extension and profiling of SysML dedicated to automotive embedded systems, AUTOSAR provides means to describe software architecture architectures. The contribution of the paper is a relationship investigation between different concepts of the two languages. Three case studies, of a position control , fuel control and a brake-by-wire system, have been used to support and validate the work. The resulting mapping scheme provides a basis for automated architecture refinements and synthesis.
