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 both academia and industry, working on constraints or on formal verification and interested in the application of constraints to formal verification.


Scope

The scope of the workshop includes topics related to the application of constraint technology to 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 is scheduled for June 26, 2009. It will be structured to allow ample time for discussion and demonstration of new tools and new problem instances.


Submissions

Submissions should be in the LNCS style and in one of the following types:

  • a regular paper of up to 15 pages;
  • a short paper of up to 4 pages, describing an industrial experience.

Papers should be e-mailed in pdf format to the workshop chair: mvelev@gmail.com

The important dates for the workshop are as follows:

Abstract submission deadlineApril 15
Paper submission deadlineApril 22
Notification of acceptanceMay 10
Camera-ready version deadlineMay 31
Workshop dateJune 26
