This paper discusses the advantages of using co-simulation in different stages of the development process for embedded automotive systems and illustrates the usage for the project STEP-X (structured development process for automotive applications). At first, an introduction to the problem of interest focused to the automotive domain is given, concerning tool requirements given by the model driven development process which can not be satisfied by only one CASE tool. A possible solution is to couple different tools within (horizontal coupling) or over different stages of the development process (vertical coupling) by co-simulation [8]. Concept and implementation approach of the Inter Tool Corporation (ITC) Framework is discussed, which has been developed at the Institute for Traffic Safety and Automation Engineering in Braunschweig (Germany). It is now commercially distributed, supported and advanced by the Extessy AG in Wolfsburg (Germany) as the ExITE (Extessy Inter Tool Engineering) Toolbox and is illustrated in a brief description. Finally, the application of co-simulation within the development process of the project STEP-X is described. STEP-X is a cooperation between the Volkswagen AG and the "Zentrum für Verkehr" at the Technical University of Braunschweig. Examples for the vertical and horizontal coupling are pointed out.
