What is the model checking problem?
A simple model-checking problem consists of verifying whether a formula in the propositional logic is satisfied by a given structure.
What is model checking approach?
Model checking is an automatic technique for verifying correctness properties of safety-critical reactive systems.
What is the advantage of model checking?
In contrast to theorem proving, model checking is completely automatic and fast, frequently producing an answer in a matter of minutes. It can be used to check partial specifications and can provide useful information about correctness even if the system has not been completely specified.
Where is model checking used?
Model checking has proven to be a tremendously successful technology to verify requirements and design for a variety of systems, particularly in hardware systems and real-time embedded and safety-critical systems.
What is state explosion problem?
As the number of state variables in the system increases, the size of the system state space grows exponentially. This is called the “state explosion problem”. Much of the research in model checking over the past 30 years has involved developing techniques for dealing with this problem.
What is LTL model checking?
This chapter discusses how a specific property specification logic, linear temporal logic (LTL), and a decision procedure for it, model checking, can be used to prove properties when the set of states reachable from an initial state in a system module is finite.
What is LTL and CTL?
CTL* is a superset of computational tree logic (CTL) and linear temporal logic (LTL). It freely combines path quantifiers and temporal operators. Like CTL, CTL* is a branching-time logic. The formal semantics of CTL* formulae are defined with respect to a given Kripke structure.
What is the full form of LTL?
Less-than-truckload, also known as less-than-load (LTL), is a shipping service for relatively small loads or quantities of freight—between 150 and 15,000 pounds.
What is model checking in software testing?
Model checking. Typically, one has hardware or software systems in mind, whereas the specification contains safety requirements such as the absence of deadlocks and similar critical states that can cause the system to crash. Model checking is a technique for automatically verifying correctness properties of finite-state systems.
What is model and property checking in logic?
This general concept applies to many kinds of logic and many kinds of structures. A simple model-checking problem consists of verifying whether a formula in the propositional logic is satisfied by a given structure. Property checking is used for verification when two descriptions are not equivalent.
Who is the founder of model checking?
Model checking began with the pioneering work of E. M. Clarke, E. A. Emerson, by J. P. Queille, and J. Sifakis. Clarke, Emerson, and Sifakis shared the 2007 Turing Award for their seminal work founding and developing the field of model checking. Model checking is most often applied to hardware designs.
What is the model checking problem in automated verification?
The problem of checking that Ms ⊨ Φ is the model checking problem [Clarke et al., 1999]. What makes model checking so appealing as a practical approach to automated verification is that it is ostensibly ‘cheaper’, computationally speaking, than the corresponding proof problem for the logic.
