Specification of real-time systems in real-time temporal interval logic

A real-time variant of temporal interval logic is proposed for the specification and reasoning of real-time systems. In the framework of the logic, it is possible to specify qualitative and quantitative aspects of temporal behaviors of systems. The formalism provides capabilities for quantitative specification of time behavior. The harmonization of temporal interval logic with real-time features leads to a very-high-level notation for the specification of real-time systems. Temporal interval logic, being event-based, also facilitates the specification of quantitative aspects of temporal behavior relative to the occurrence of events in a given context. The use of the formalism is shown for three examples of real-time system specification: a packet network with rerouting, a traffic-light controller, and a time-constrained broadcast bus protocol.<
