Software architecture analysis based on statechart semantics

High assurance architecture-based and component-based software development relies fundamentally on the quality of the components of which a system is composed and their configuration. Analysis over those components and their integration as a system plays a key role in the software development process. This paper describes an approach to develop and assess architecture and component-based systems based on specifying software architecture augmented by statecharts representing component behavioral specifications. The approach is applied for the C2 style and associated ADL and is supported within a quality-focussed environment, called Argus-I, which assists specification-based analysis and testing at both the component and architecture levels.
