This volume contains the proceedingsof the 23rdeditionof this conference held inSnowbird,Utah, USA, during July14–20,2011.The conferenceincluded twoworkshopdays,atutorial day, and four days for the main program. At CAV 2009, Bob Kurshan approached us with the idea of holding CAV 2011 in Salt Lake City. Encouraged by the enthusiastic support from late Amir Pnueli, we had little hesitation in agreeing to Bob’s proposal. While the initial proposalwastoorganizetheconferenceonthecampusoftheUniversityofUtah, weeventuallydecidedtoholditattheSnowbirdresortnearSaltLakeCity.Our decision was motivated by the dual desire to showcase the abundant natural beauty of Utah and to provide a collegial atmosphere similar to a Dagstuhl workshop. We are happy to report that CAV is thriving, as evidenced by the large number of submissions. We received 161 submissions and selected 35 regular and20 toolpapers.We appreciate the diligence ofour ProgramCommittee and ourexternalreviewersduetowhichall(excepttwo)papersreceivedatleastfour reviews. A big thank you to all our reviewers! The conference was preceded by the eight affiliated workshops: – The 4th International Workshop on Numerical Software Verification (NSV 2011), Thursday, 7/14 – 10thInternationalWorkshoponParallelandDistributed Methods in Verifi- cations (PDMC 2011), Thursday, 7/14 – The 4th International Workshop on Exploiting Concurrency Efficiently and Correctly (EC2 2011), 7/14-7/15 – FrontiersinAnalogCircuitSynthesisandVerification(FAC2011),7/14-7/15 – International Workshop on Satisfiability Modulo Theories, including SMT- COMP (SMT 2011), 7/14-7/15 – 18th International SPIN Workshop on Model Checking of Software (SPIN 2011), 7/14-7/15 – Formal Methods for Robotics and Automation (FM-R 2011), 7/15 – Practical Synthesis for Concurrent Systems (PSY 2011), 7/15 In addition to the presentations for the accepted papers, the conference also featured four invited talks and four invited tutorials. – Invited talks: • Andy Chou (Coverity Inc.): “Static Analysis Tools in Industry: Notes from the Front Line” VI Preface • VigyanSinghalandPrashantAggarwal(OskiTechnology):“UsingCov- erage to Deploy Formal Verification in a Simulation World” • Vikram Adve (University of Illinois at Urbana-Champaign): “Parallel Programming Should Be and Can Be Deterministic-by-default” • Rolf Ernst (TU Braunschweig):“FormalPerformanceAnalysis in Auto- motive Systems Design: A Rocky Ride to New Grounds” – Invited tutorials: • Shuvendu Lahiri (Microsoft Research): “SMT-Based Modular Analysis of Sequential Systems Code” • Vijay Ganesh (Massachussetts Institute of Technology): “HAMPI: A String Solver for Testing, Analysis and Vulnerability Detection” • Ranjit Jhala (University of California at San Diego): “Using Types for Software Verification” • Andre Platzer (Carnegie Mellon University): “Logic and Compositional Verification of Hybrid Systems” A big thank you to all our invited speakers! We thank the members of the CAV Steering Committee —Michael Gordon, Orna Grumberg, Bob Kurshan, and Ken McMillan— for their timely advice on various organizational matters. Neha Rungta, our Workshop Chair, smoothly handledtheorganizationoftheworkshops.EricMercer,ourLocalArrangements Chair, set up the registrationportal at Brigham Young University. Sandip Ray, our Publicity Chair, helped publicize CAV 2011. We thank Aarti Gupta, past CAV Chair, for her help and advice in running the conference and maintaining its budget. WethankGeofSawayaformaintainingtheCAV2011website.Wearegrate- ful to Wendy Adamson for arranging the beautiful Cliff Lodge facility at an affordable price and really making the budget work in our favor. We thank Al- fredHofmannofSpringerforpublishingthepaperandUSBproceedingsforCAV 2011.We thank Andrei Voronkov and his team for offering us EasyChair which has proven invaluable at every juncture in conducting the work of CAV. We thank the office staff of the School of Computing, University of Utah, especially Karen Feinauer and Chris Coleman, for allowing us to use the school resources for managing CAV activities. We are especially grateful to our corporate sponsors —Microsoft Research, Coverity, Google, NEC Research, Jasper, IBM, Intel, Fujitsu, and Nvidia— for their donations. We are also grateful to Judith Bishop and Wolfram Schulte of MicrosoftResearchfortheirsubstantialfinancialbackingofCAV.Wealsothank LenoreZuck,NinaAmla,andSolGreenspanwhohelpedwithobtaininganNSF travel award.
