SPECIFICATION-DRIVEN DESIGN OF EMBEDDED SYSTEMS

摘要

The paper presents an approach to formal specification, verification and prototyping of networked embedded software system applications ranging from large information systems down to small components embedded e.g. in mobile devices. Main attention focuses both on architectural and behavioral specifications of either reactive or real-time activities utilizing either structured or object-oriented approach depending on application requirements. The design approach fully respecting such requirements can eliminate not only behavioral and structural faults but also security flaws caused by design errors. Reflecting current trends in engineering software-intensive systems, this contribution discusses in more detail executable specifications and rapid prototyping for structured design, and structural specifications and verifications for object-oriented design. The paper presents Asynchronous Specification Language and Class Specification Language developed for that purpose.
