A higher level of behavioural specification: An example in interval temporal logic

Abstract

This paper reports on the use of Moszkowski's Tempura — an executable version of Interval Temporal Logic — in developing behavioural specifications for digital circuits. A Tempura model for a commercial avionics circuit is described, showing how Tempura facilatates a well-structured executable specification, incorporating timing characteristics, but expressed at a high level of abstraction. A second version shows the use of temporal projection to develop a model at a finer temporal granularity.
