One challenge of the TEODACS project is to understand the challenges related to the design, integration and validation of communication architectures based on the FlexRay protocol. Based on a detailed explanation of the time-triggered concepts, the focus of this paper is set on the integration

The trend of replacing traditional mechanical systems by modern embedded systems, and the launch of automotive multi-core systems enable deployment of more advanced control strategies. However, these applications require different safety concepts with different levels of criticality; and providing consistency of the safety concept during the entire product lifecycle is a tedious task. Additionally, new automotive safety standards, such as ISO 26262, and the de-facto industry standard AUTOSAR require efficient and consistent product development and tool support. The aim of the presented work is to establish a model-driven system and safety-engineering framework to support the seamless description of safety-critical systems, from requirements at the system level to final component implementation. Zusammenfassung Die Komplexität von Embedded Systems im Automobil hat in den letzten Jahren enorm zugenommen. Der Trend, etablierte, mechanische Systeme durch moderne eingebettete Controller zu ersetzen und die Einführung von speziell für den Einsatz im Kraftfahrzeug konzipierten Multi-Core-Systemen ermöglicht die Entwicklung von ausgeklügelten Fahrassistenz- und Komfortfunktionen. Allerdings fordern diese Anwendungen unterschiedliche Sicherheitskonzepte mit unterschiedlichen Kritikalitätsstufen und die Einhaltung dieser Richtlinien während der gesamten Produktentwicklung. Die Einführung des neuen Automotive-Sicherheitsstandards ISO 26262 und der Industriestandard AUTOSAR erfordern zusätzlich effiziente und konsequente Produktentwicklung und Werkzeugunterstützung. Das Ziel der vorgestellten Arbeit ist es, ein Modell-basiertes Entwicklungsframework zur Unterstützung der durchgängigen Beschreibung von sicherheitskritischen Systemen von Defintion der Anforderungen auf Systemebene zur Komponentenentwicklung zu ermöglichen.

However, these applications require different safety concepts with different levels of criticality; and providing consistency of the safety concept during the entire product lifecycle is a tedious task. The aim of this paper is to enhance a modeldriven systems and safety engineering framework for multi-core systems, enabling the seamless description of the system, from requirements at the system level down to software component implementation.

However, effects occurring e.g. on the physical level may impact the whole system and cannot be captured by using only high abstracted models. Co-simulation is a possible solution for this problem. It enables the combination of an abstracted, system

Paradoxically, the ongoing integration efforts at component level have led to complex local interactions between the subsystems that are difficult to analyze globally. We present in this work a test environment for automotive networks that goes beyond the component
