Cooperation between the {B} method and the automata theory to check the component interoperability

Abstract

International audienceComponent interoperability is one of the essential issues in the component based development, since it allows the composition of reusable heterogenous components developed by different people. In this paper, we propose an approach to formally verify component interoperability at signature, semantics, and protocol levels. It is based on the use of the B formal method for specifying component interfaces and finite transition systems for specifying component protocols. The verification is done with the B theorem prover and the verification of the simulation relation between transition systems. This approach allows to decide whether two components can interoperate if assembled together and whether a component can be replaced by another component
