Space-Efficient Bounded Model Checking

چکیده
Current algorithms for bounded model checking use SAT methods for checking satisfiability of Boolean formulae. Methods based on the validity of Quantified Boolean Formulae (QBF) allow an exponentially more succinct representation of formulae to be checked, because no “unrolling” of the transition relation is required. These methods have not been widely used, because of the lack of an efficient decision procedure for QBF. In this paper we present an algorithm for bounded model checking that uses as succinct representation of formulae as possible with QBF-based techniques. We also provide a comparison of our technique with SAT-based and QBF-based ones, using a few available solvers, on real-life industrial benchmarks.

A Hybrid Meta-heuristic Approach to Cope with State Space Explosion in Model Checking Technique for Deadlock Freeness
Model checking is an automatic technique for software verification through which all reachable states are generated from an initial state to finding errors and desirable patterns. In the model checking approach, the behavior and structure of system should be modeled. Graph transformation system is a graphical formal modeling language to specify and model the system. However, modeling of large s...
متن کاملReachability checking in complex and concurrent software systems using intelligent search methods
Software system verification is an efficient technique for ensuring the correctness of a software product, especially in safety-critical systems in which a small bug may have disastrous consequences. The goal of software verification is to ensure that the product fulfills the requirements. Studies show that the cost of finding and fixing errors in design time is less than finding and fixing the...
متن کاملCombining Partial Order Reduction with Bounded Model Checking
Model checking is an efficient technique for verifying properties on reactive systems. Partial-order reduction (POR) and symbolic model checking are two common approaches to deal with the state space explosion problem in model checking. Traditionally, symbolic model checking uses BDDs which can suffer from space blowup. More recently bounded model checking (BMC) using SAT-based procedures has b...
متن کاملEfficient Saturation-based Bounded Model Checking of Asynchronous Systems
Formal verification is becoming a fundamental step in assuring the correctness of safety-critical systems. However, due to these systems being often asynchronous and even distributed, their behaviour can be very complex. Thus, their verification necessitates methods that can deal with huge or even infinite state spaces. In this paper we present how the integration of two advanced algorithms for...
متن کاملThe parameterized space complexity of model-checking bounded variable first-order logic
The parameterized model-checking problem for a class of first-order sentences (queries) asks to decide whether a given sentence from the class holds true in a given relational structure (database); the parameter is the length of the sentence. In 1995 Vardi observed a polynomial time algorithm deciding the model-checking problem for queries with a bounded number of variables. We study its parame...
