Abstract

We present a compositional methodology for specification and proof using Interval Temporal Logic (ITL). After given an introduction to ITL, we show how fixpoints of various ITL operators provide a flexible way to modularly reason about safety and liveness. In addition, some new techniques are described for compositionally transforming and refining ITL specifications. We also consider the use of ITL's programming language subset Tempura as a tool for testing the kinds of specifications dealt with here.
