Computer Aided Verification : 21st International Conference

This volume contains the proceedings of the 21st International Conference on Computer-Aided Veri?cation (CAV) held in Grenoble, France, between June 28 and July 2, 2009. CAV is dedicated to the advancement of the theory and practice of computer-aided formal analysis methods for hardware and software systems. Its scope ranges from theoretical results to concrete applications, with an emphasis on practical veri?cation tools and the underlying algorithms and techniques. Everyinstanceofaconferenceisspecialinitsownway.ThisCAVisspecialfor at least two reasons: ?rst, it took place in Grenoble, the place where the CAV series started 20 years ago. Secondly, there was a particularly large number of paper submissions: 135 regular papers and 34 tool papers, summing up to 169 submissions. They all went through an active review process, with each submissionreviewedbyfourmembersoftheProgramCommittee.Wealsosought external reviews from experts in certain areas. Authors had the opportunity to respond to the initial reviews during an author response period. All these inputs wereusedbytheProgramCommitteeinselectinga?nalprogramwith36 regular papers and 16 tool papers. In addition to the presentation of these papers, the program included the following: - Four invited tutorials: - Rachid Guerraoui (EPFL Lausanne, Switzerland): Transactional M- ory: Glimmer of a Theory. - Jaeha Kim (Stanford, USA): Mixed-Signal System Veri?cation: A High- Speed Link Example. - Jean Krivine (Institut des Hautes Etudes Scienti?ques, France): M- elling Epigenetic Information Maintenance: A Kappa Tutorial. - JosephSifakis (CNRS-VERIMAG, France): Component-BasedConstr- tion of Real-Time Systems in BIP.
