Integrating Different Views to Develop Complex Real-Time Systems

Abstract Views are vehicles for separation of concerns. They allow developer to address only those concerns or criteria that are of interest, ignoring others that are unrelated. For complex real-time systems, there are usually multiple parties involved in system development, which are concerned with different views of a system. This paper discusses a single design methodology that covers all phases of the life cycle, ensuring that specific real-time system requirements of the software will be met. This methodology emphasize the identification of different views on the system under construction. Each of these views can be constructed using common notations and techniques, including structured notations as well as formal specification. The proposed methodology is illustrated by specifying a heater system.
