Modern Cyber-Physical Systems are often driven bya plethora of controllers that are connected with each other andtheir environment. To guarantee a safe and robust execution ofthe systems, their control units have to strictly fulfill certainproperties which calls for the use of formal analysis methods inthe software development process. We present the combinationof the model-based engineering technique Reactive Blocks andthe spatiotemporal analysis tool BeSpaceD facilitating the formalverification of controller software.
