The formal verification of properties in reactive real-time systems is crucial, as these systems are often safety-critical ones. Refinement is a relevant operation in synchronous languages. In this paper, we argue that, in the synchronous approach to the design and implementation of reactive real-time systems, modular verification (from the point of view of the refining program) is best achieved with observers
