Abstract

Symbolic model checking is a powerful formal-verification technique which has been used to analyze many hardware systems. In this paper we present our experiences in applying symbolic model checking to software specifications of reactive systems. We have conducted two in depth case studies: one, using the specification of TCAS II (Trafic Alert and Collision Avoidance System II), and the other using a model of an aircraft electrical system. Based on these case studies, we have gained significant experience in how model checking can be used in to analyze software specifications, and have also overcome a number of performance bottlenecks to make the analysis tractable.

The emphasis of this paper is the uses of model checking in the analysis of specifications. We will discuss the types of properties which we were able to evaluate in our case studies. These include specific errors we were able to identify, as well as general properties we were able to establish for the systems. We will also discuss, in more general terms, the potential uses of symbolic model checking in the development process of software specifications.
