Computer-Aided Verification

"Computer-Aided Verification" is a collection of papers that begins with a general survey of hardware verification methods. Ms. Gupta starts with the issue of verification itself and develops a taxonomy of verification methodologies, focusing especially upon recent advances. Although her emphasis is hardware verification, most of what she reports applies to software verification as well. Graphical presentation is coming to be a "de facto" requirement for a "friendly" user interface. The second paper presents a generic format for graphical presentations of coordinating systems represented by automata. The last two papers as a pair, present a variety of generic techniques for reducing the computational cost of computer-aided verification based upon explicit state enumeration. Both give techniques which can reduce the required computational memory: the first of the two gives a time-space trade-off, while the second gives a technique which trades space for a (sometimes predictable) probability of error. "Computer-Aided Verification" is an edited volume of original research. This research work has also been published as a special issue of the journal "Formal Methods on System Design, 1:2-3".
