Supporting verification-driven incremental distributed design of components

Software systems are usually formed by multiple components which interact with one another. In large systems, components themselves can be complex systems that need to be decomposed into multiple sub-components. Hence, system design must follow a systematic approach, based on a recursive decomposition strategy. This paper proposes a comprehensive verification-driven framework which provides support for designers during development. The framework supports hierarchical decomposition of components into sub-components through formal specification in terms of pre- and post-conditions as well as independent development, reuse and verification of sub-components.
