Event B Development of a Synchronous AADL Scheduler

This paper presents the modelisation of the semantics of a subset of the architecture description language AADL using Event-B. Elements of the semantics of the considered subset are gradually introduced in order to make possible the traceability of the formal text against the informal specification. Starting from a very general computational model, we incrementally add elements of AADL by constraining or instantiating it and finally introduce a family of schedulers. The Rodin platform is used to prove the correctness of this development.
