These are the conference proceedings of the 4th Haifa Veri?cation Conference, held October 27-30, 2008 in Haifa, Israel. This international conference is a unique venue that brings together leading researchers and practitioners of both formal and dynamic veri?cation, for both hardware and software systems. This year's conference extended the successes of the previous years, with a largejumpinthenumberofsubmitted papers. Wereceived49totalsubmissions, with many more high-quality papers than we had room to accept. Submissions came from 19 di?erent countries, re?ecting the growing international visibility of the conference. Of the 49 submissions, 43 were regular papers, 2 of which were later withdrawn, and 6 were tool papers. After a rigorous review process, in which each paper received at least four independent reviews from the dist- guished Program Committee, we accepted 12 regular papers and 4 tools papers for presentation at the conference and inclusion in this volume. These numbers give acceptance rates of 29% for regular papers and 67% for tool papers (34% combined) - comparable to the elite, much older, conferences in the ?eld. A Best Paper Award, selected on the basis of the reviews and scores from the Program Committee, was presented to Edmund Clarke, Alexandre Donz e, and AxelLegayfortheirpaperentitled"StatisticalModelCheckingofMixed-Analog Circuits with an Application to a Third-Order Delta-Sigma Modulator. " The refereed program was complemented by an outstanding program of - vited talks, panels, and special sessions from prominent leaders in the ?eld."

These are the proceedings of the ?fth international conference, Formal Methods in Computer-Aided Design (FMCAD), held 15-17 November 2004 in Austin, Texas, USA. The conference provides a forum for presenting state-of-the-art tools, methods, algorithms, and theory for the application of formalized r- soning to all aspects of computer-aided system design, including speci?cation, veri?cation, synthesis, and testing.

We are delighted to report that our researchcommunitycontinuesto?ourish: wereceived69papersubmissions, with many more high-quality papers than we had room to accept. After a rigorous review process, in which each paper received at least three, and typically four or more, independent reviews, we accepted 29 papers for the conference and inclusion in this volume. The conference also included invited talks from Greg Spirakis of Intel Corporation and Wayne Wolf of Princeton University. A conference of this size requires the contributions of numerous people. On the technical side, we are grateful to the program committee and the additional reviewers for their countless hours reviewing submissions and ensuring the int- lectual quality of the conference. We would also like to thank the steering c- mittee for their wisdom and guidance. On the logistical side, we thank Christa Mace for designing our website and attending to countless organizational tasks. And we thank our corporate sponsors - AMD, IBM, Intel, and Synopsys - for ?nancial support that helped make this conference possible.

This book consitutes the refereed proceedings of the 10th International Conference on Computer Aided Verification, CAV'98, held in Vancouver, BC, Canada, in June/July 1998. The 33 revised full papers and 10 tool papers presented were carefully selected from a total of 117 submissions. Also included are 11 invited contributions. Among the topics covered are modeling and specification formalisms; verification techniques like state-space exploration, model checking, synthesis, and automated deduction; various verification techniques; applications and case studies, and verification in practice.
