This volume contains the proceedings of the 3rd Haifa Veri?cation Conference (HVC 2007),whichtookplacein Haifa during October 2007.HVC isa forumfor researchers from both industry and academia to share and advance knowledge in the veri?cation of hardware and software systems. Academic research in veri?cation is generally divided into two paradigms formal veri?cation and dynamic veri?cation (testing). Within each paradigm, di?erent algorithms and techniques are used for hardware and softwaresystems. Yet,attheircore,allofthesetechniquesaimtoachievethesamegoalofensuring the correct functionality of a complicated system. HVC is the only conference that brings together researchers from all four ?elds, thereby encouraging the migration of methods and ideas between domains. With this goal in mind we established the HVC Award. This award rec- nizes a promising contribution to veri?cation published in the last few years. It is aimed at developments that signi?cantly advance the state of the art in veri?cation technology and show potential for future impact on di?erent ver- cation paradigms. The winners of the HVC Award are chosen by an indep- dent committee with experts from all ?elds of veri?cation both formal and dynamic, software and hardware. The winners of the 2007 HVC Award were Corina Pas? ? areanu and Willem Visser, for their work on combining static and dynamic analysis. This year we received 32 submissions, out of which 15 were accepted after a thorough review conducted by the Program Committee (PC) and additional reviewers.Eachpaper wasreviewedby atleastthree reviewers,sometimes more.
