Co-modelling and Co-simulation in Embedded Systems Design

The collaborative development of an embedded system requires productive interaction between engineers from very different backgrounds. Control engineering and software engineering have matured over many decades, each with its own philosophy, methods and terminology, and so it is necessary to clarify the common ideas that underpin co-modelling and co-simulation. This chapter introduces the concepts of co-modelling and co-simulation, including notions of system, model and co-model, simulation and co-simulation. It also describes the ways in which co-modelling and co-simulation can be integrated with established systems and software life cycle processes such as IEEE 15288 and IEEE 12207.
