This book describes the methodology and accompanying technology for reducing the costs of validation of changes by introducing automatic techniques to analyze and test software increments. It builds a unified approach to efficient and reliable validation of changes and upgrades, and may be used as a research monograph and a reference book.

This volume constitutes the thoroughly refereed post-conference proceedings of the 6th International Conference on Verified Software: Theories, Tools and Experiments, VSTTE 2014, held in July 2014 at the Vienna Summer of Logic in Vienna, Austria, as an associated event of CAV 2014, the International Conference on Computer-Aided Verification.

The two-volume set LNCS 9206 and LNCS 9207 constitutes the refereed proceedings of the 27th International Conference on Computer Aided Verification, CAV 2015, held in San Francisco, CA, USA, in July 2015. The total of 58 full and 11 short papers presented in the proceedings was carefully reviewed and selected from 252 submissions.

A decision procedure is an algorithm that, given a decision problem, terminates with a correct yes/no answer. Here, the authors focus on theories that are expressive enough to model real problems, but are still decidable. Specifically, the book concentrates on decision procedures for first-order theories that are commonly used in automated verification and reasoning, theorem-proving, compiler optimization and operations research. The techniques described in the book draw from fields such as graph theory and logic, and are routinely used in industry. The authors introduce the basic terminology of satisfiability modulo theories and then, in separate chapters, study decision procedures for each of the following theories: propositional logic; equalities and uninterpreted functions; linear arithmetic; bit vectors; arrays; pointer logic; and quantified formulas. They also study the problem of deciding combined theories and dedicate a chapter to modern techniques based on an interplay between a SAT solver and a decision procedure for the investigated theory.This textbook has been used to teach undergraduate and graduate courses at ETH Zurich, at the Technion, Haifa, and at the University of Oxford. Each chapter includes a detailed bibliography and exercises. Lecturers' slides and a C++ library for rapid prototyping of decision procedures are available from the authors' website.

Dieses Einführungswerk in die Digitaltechnik wurde speziell für Bachelorstudenten entwickelt. Es enthält viele auf den Anfänger zugeschnittene praktische Anwendungen. Folgende Aspekte sind einmalig: Tool-orientierter Ansatz - Verwendung der Hardwarebeschreibungssprache Verilog - Einführung in systematische Methoden zur Fehlersuche - Geringe Anforderungen an die mathematischen Vorkenntnisse - Ein vereinfachter X86 IA32-Prozessor als AnwendungsbeispielDie vorgestellten Beispiele werden mit Hilfe von Tools wie XILINX ISE und MentorGraphics ModelSim in echte Schaltungen umgesetzt. Diese Tools werden auch im industriellen Alltag eingesetzt. Im Internet werden weitere Übungen, realisierte Beispiele sowie Animationen angeboten. Für Dozenten stehen Folien zum Abrufen bereit.

This book constitutes the thoroughly refereed post-conference proceedings of the 6th International Haifa Verification Conference, HVC 2010, held in Haifa, Israel in October 2010.The 10 revised full papers presented together with 7 invited papers were carefully reviewed and selected from 30 submissions. The papers address all current issues, challenges and future directions of verification for hardware, software, and hybrid systems and have a research focus on hybrid methods and the migration of methods and ideas between hardware and software, static and dynamic analysis, pre- and post-silicon.

The techniques described in the book draw from fields such as graph theory and logic, and are routinely used in industry.The authors introduce the basic terminology of SAT, Satisfiability Modulo Theories (SMT) and the DPLL(T) framework.
