Boolean satisfiability is a NP-hard problem in computer theoretic science. There are two types of SAT solvers, random local solver and DPLL-based complete solver. Some people have proposed hybrid SAT solvers that combined the advantage of them both. They have successfully applied them to solve large or hard random SAT problems and circuit related problems. However, these solvers often find over-satisfying...
All-solution Boolean satisfiability (SAT) solver has been widely used throughout the EDA industry fields, such as formal verification, circuit synthesis and automatic test pattern generation. Exploiting structure information especially observability donpsilat cares(ODCs) of circuits can improve the efficiency of SAT solvers. The authors converted the ODC property of signal to clauses of CNF formula...
