Often, there exists mismatch among tools that are used for structural, functional, and execution modeling of vehicular embedded real-time systems in the industry. Building a seamless tool chain to support model- and component-based development of these systems with different, and sometimes independent, tools is challenging. Within this context, we investigate the challenges related to modeling, analyzing, and exchanging end-to-end timing information. We target domain specific models like EAST-ADL supplemented by the Timing Augmented Description Language; and component and execution models that are already used in the industry such as the Rubus Component Model.
