Interval Temporal Logic
Appearance
Interval Temporal Logic (ITL) is a form of temporal logic that includes the concept of time intervals. It was originally developed by Ben Moszkowski, initially for his thesis at the University of Cambridge. ITL includes both propositional and first-order logical reasoning about discrete time periods and is useful in the formal description of hardware and software for computer-based systems. Tools are available to aid in this process. Tempura provides an executable ITL framework. Compositionality is a significant issue and consideration in the design of ITL.
