CLAIRE: an event-driven simulation tool for test and validation of software programs

Malfunctions of systems in domains such as medicine, avionics, traffic control, defense and nuclear applications can cause human injuries. Test and validation of such systems is a difficult task, because many situations cannot be safely reproduced. Simulation makes possible to assess the correctness of a safety-critical system, even in dangerous situations. This paper presents CLAIRE, a purely software simulation tool with graphic facilities for system modelling, designed for test, validation and non-intrusive dynamic analysis of real time applications.
