Call for Papers: CFV'06 Fourth International Workshop on Constraints in Formal Verification (CVF'06), http://www.easychair.org/FLoC-06/CFV.html Paper submission deadline: June 5 CFV'06 will be held on August 22, and will be part of the 3rd International Joint Conference on Automated Reasoning (IJCAR'06), http://ijcar06.uni-koblenz.de/ a conference at the Federated Logic Conference (FLoC) http://research.microsoft.com/floc06/ in Seattle, Washington, August 2006 Overview Formal verification is of crucial significance in the development of hardware and software systems. In the last few years, tremendous progress was made in both the speed and capacity of constraint technology. Most notably, SAT solvers have become orders of magnitude faster and capable of handling problems that are orders of magnitude bigger, thus enabling the formal verification of more complex computer systems. As a result, the formal verification of hardware and software has become a promising area for research and industrial applications. The main goals of the Constraints in Formal Verification workshop are to bring together researchers from the CSP/SAT and the formal verification communities, to describe new applications of constraint technology to formal verification, to disseminate new challenging problem instances, and to propose new dedicated algorithms for hard formal verification problems. This workshop will be of interest to researchers from academia and industry, working in constraints or in formal verification and interested in the application of constraints in formal verification. Scope The scope of the workshop includes topics related with the application of constraint technology in formal verification, namely: application of constraint solvers to hardware verification; application of constraint solvers to software verification; dedicated solvers for formal verification problems; challenging formal verification problems. Delivery The workshop will be scheduled for one full day. We expect to structure the workshop to allow ample time for discussion and demonstration of new tools and new problem instances. Submissions Submissions can include one of the following: -A workshop paper of up to 15 pages in LNCS format. -A short paper of up to 4 pages, in LNCS format, describing an industrial experience.
