This article presents a novel way to model safety critical systems hierarchically. An information flow diagram as high level and finite automatons as low level model are combined. With these models, scenarios leading to dangerous failures as well as spurious shutdowns can be generated. Furthermore, we will show how to extract the different scenarios out of the model in a very efficient way using different BDD-techniques. Finally, we will present some related work.
