The complexity of modern systems is reflected in a proportionate increase in the complexity of their design and verification. Formal analysis methods are of particular interest because they provide the mathematical foundation necessary for rigorous analysis; successful formal analysis of a system provides a high level of assurance of correctness and conformance with specifications. Unfortunately for a number of reasons, formal analysis techniques have failed to scale to large systems. In traditional engineering disciplines, decomposition and component-based design activities have contributed substantially to effective design of large systems. Consequently, this paper presents some proof obligations that perform partial correctness checks on hierarchically designed systems. Since the obligations are applied locally, they avoid the state explosion associated with formal analysis of a large system. The obligations represent initial steps towards the goal of decompositional verification of designs
