Finding bugs in software with a constraint solver
… on a three-step translation: from code to a formula in Alloy, which is a first-order relational logic, then to a propositional formula, and finally to conjunctive normal form. An off-the-shelf SAT solver is then used to find a solution that constitutes a counterexample. Modularity comes at …

Generalized Satisfiability Problems
… problem is the satisfiability problem of propositional formulas (SAT). Here we get a propositional formula as an input and it must be decided whether an assignment for the propositional variables exists, such that this assignment satisfies the given formula. The intensive study of NP led …

Exploring Constraint Satisfiability Techniques in Formal Verification
Due to the widespread demands for efficient Propositional Satisfiability (SAT) solvers and its derivatives in Electronic Design Automation applications, methods to boost the performance of the SAT solver are highly desired. This dissertation aims to enhance the performance of SAT and related SAT …

Enhancing SAT-based Formal Verification Methods using Global Learning
… signal relationships into the original CNF formula of the circuit under verification and hence reduce the complexity of the SAT instance. This efficient and effective preprocessing quickly builds up the implication graph for the circuit under verification, yielding a large set of logic …
