Modern material handling systems (MHS) are complex systems which are controlled by various control units on different automation levels. The design of the MHS facility layout and the development of the control units require the application of different CAE tools but simulation and virtual commissioning does currently not play a significant role because(More)
Simulation plays the most important role for the verification of digital circuits. Designers demand more and more speed for their simulation processes. Therefore, we have worked out an approach to accelerate logic simulation by using prototype boards. We developed a novel simulator/hardware interface to achieve a significant speed-up. A speed-up of about(More)
Programmable logic controllers (PLCs) are applied in a wide field of application and, especially, for safety-critical controls. Thus, there is the demand for high reliability of PLCs. Moreover, the increasing complexity of the PLC programs and the short time-to-market are hard to cope with. Formal verification techniques such as model checking allow for(More)
Kurzfassung Ausgehend von einem Drei-Ebenen-Modell zur Beschreibung komplexer dynamischer Systeme werden die Modellklassen vorgestellt, die mit dem Multi-Level-Simulator KOSIM simuliert werden können. Auf der analytischen Ebene sind das DG-Systeme, Zustandsglei-chungen, elektrische Schaltungen, Signalflußgraphen und Blockschaltpläne. Die übergeord-nete(More)

For covering the real-time characteristics of an automation system during model-based design it is essential to model not only the function but also the behaviour of the control programs running on a real-time controller. This paper introduces an approach to the modelling and evaluation of the functional and time behaviour of Programmable Logic Controllers(More)
Wireless sensor networks (WSN) get increasing importance in different application areas. In building automation, applications on WSN are expected to utilize a large number of nodes in a heterogeneous environment. They are too complex to be developed in the traditional way of prototyping and debugging. In fact, new techniques are needed to support the design(More)
