Satisfiability Modulo Theories (SMT) refers to the problem of determining whether a first-order formula is satisfiable with respect to some logical theory. Solvers based on SMT are used as back-end engines in model checking applications such as bounded, interpolation-based, and predicate abstraction-based model checking. After a brief illustration of these… (More)

A malware detector is a system that attempts to determine whether a program has malicious intent. In order to evade detection, malware writers (hackers) frequently use obfuscation to morph malware. Malware detectors that use a pattern-matching approach (such as commercial virus scanners) are susceptible to obfuscations used by hackers. The fundamental… (More)

We will begin with synchronous composition, an abstraction that has been very effectively used in hardware design and is gaining popularity in software design. A system is a function that accepts an input signal and yields an output signal. The domain and range of the system function are sets of signals, which themselves are functions. Parameters may affect… (More)

Sketching is a software synthesis approach where the programmer develops a partial implementation - a sketch - and a separate specification of the desired functionality. The synthesizer then completes the sketch to behave like the specification. The correctness of the synthesized implementation is guaranteed by the compiler, which allows, among other… (More)

—The classical formulation of the program-synthesis problem is to find a program that meets a correctness specification given as a logical formula. Recent work on program synthesis and program optimization illustrates many potential benefits of allowing the user to supplement the logical specification with a syntactic template that constrains the space of… (More)

In this paper, we describe the modeling and veriication of out-of-order microprocessors with unbounded resources using an expressive , yet eeciently decidable, quantiier-free fragment of rst order logic. This logic includes uninterpreted functions, equality, ordering, constrained lambda expressions, and counter arithmetic. UCLID is a tool for specifying and… (More)

A significant challenge to the formal validation of software-based industrial control systems is that system requirements are often imprecise, non-modular, evolving, or even simply unknown. We propose a framework for mining requirements from the closed-loop model of an industrial-scale control system, such as one specified in the Simulink modeling language.… (More)

Given a CNF formula and a weight for each assignment of values to variables, two natural problems are weighted model counting and distribution-aware sampling of satisfying assignments. Both problems have a wide variety of important applications. Due to the inherent complexity of the exact versions of the problems, interest has focused on solving them… (More)
