    Towards compositional verification of synchronous reactive systems
    (2021) Chabane, Sarah; Ameur-Boulifa, Rabéa; Mezghiche, Mohamed
    We present work towards a compositional design approach that will lead designers to develop safe reactive systems. To this end, we extend the theory of I/O-automata that is widely used for modelling reactive systems with composition operator required for dealing with a specific assembly of such systems: systems that consist of a chain of components arranged so that the output of each component is the input of the next, and behave like pipelines. We show that the proposed composition operator ensures semantics preserving of reactive components models. The paper presents a general result on correct-by-construction approach for reactive systems design
