Abstract

The complexity of embedded automotive systems calls for a more rigorous approach to system development compared to current state of practice. A critical issue is the management of the engineering information that defines the embedded system. Development time, cost efficiency, quality and most importantly, dependability, all benefit from appropriate information management. System modeling based on an architecture description language is a way to keep the engineering information in one information structure. The EAST-ADL was developed in the EAST-EEA project (www.east-eea.org) and is an architecture description language for automotive embedded systems. It is currently refined in the ATESST project (www.atesst.org). This chapter describes how dependability is addressed in the EAST-ADL. The engineering process defined in the EASIS project (www.easis-online.org) is used as an example to illustrate the support for engineering processes in EAST-ADL.
