The purpose of the book is to train verification engineers on the breadth of technologies available and to give them a utilitarian methodology for making effective use of those technologies. The book is easy to understand and a joy to read. Its organization follows a ‘typical’ verification project from inception to completion, (planning to closure). The book elucidates concepts using non-technical terms and clear entertaining explanations. Analogies to other fields are employed to keep the book light-hearted and interesting.

CHARME’99 is the tenth in a series of working conferences devoted to the dev- opment and use of leading-edge formal techniques and tools for the design and veri?cation of hardware and systems. Previous conferences have been held in Darmstadt (1984), Edinburgh (1985), Grenoble (1986), Glasgow (1988), Leuven (1989), Torino (1991), Arles (1993), Frankfurt (1995) and Montreal (1997). This workshop and conference series has been organized in cooperation with IFIP WG 10. 5. It is now the biannual counterpart of FMCAD, which takes place every even-numbered year in the USA. The 1999 event took place in Bad Her- nalb, a resort village located in the Black Forest close to the city of Karlsruhe. The validation of functional and timing behavior is a major bottleneck in current VLSI design systems. A predominantly academic area of study until a few years ago, formal design and veri?cation techniques are now migrating into industrial use. The aim of CHARME’99 is to bring together researchers and users from academia and industry working in this active area of research. Two invited talks illustrate major current trends: the presentation by G ́erard Berry (Ecole des Mines de Paris, Sophia-Antipolis, France) is concerned with the use of synchronous languages in circuit design, and the talk given by Peter Jansen (BMW, Munich, Germany) demonstrates an application of formal methods in an industrial environment. The program also includes 20 regular presentations and 12 short presentations/poster exhibitions that have been selected from the 48 submitted papers.

This book constitutes the refereed proceedings of the international symposium Formal Methods Europe, FME 2002, held in Copenhagen, Denmark, in July 2002. The 31 revised full papers presented together with three invited contributions were carefully reviewed and selected from 95 submissions. All current aspects of formal methods are addressed, from foundational and methodological issues to advanced application in various fields.

This book fills the critical need for an in-depth technical reference providing the methods and techniques for building and maintaining confidence in many varities of system software. The intent is to help develop reliable answers to such critical questions as: 1) Are we building the right software for the need? and 2) Are we building the software right? Software Verification and Validation: An Engineering and Scientific Approach is structured for research scientists and practitioners in industry. The book is also suitable as a secondary textbook for advanced-level students in computer science and engineering.
