Abstract

This paper proposes a method for temporal verification of real-time multitasking applicationproperties based on a communicating timed automata IF language. The properties are divided into two kinds: local properties of application elements like object creation/destruction, object length, task deadlocks and secondly global properties such as data age, deadline, and time interval verification. These properties are represented by observer automata and verified by the IF2C tool exhaustive simulation. The notion of phrase is used to reduce the IF representation graph by partitioning the application on the basis of phases.
