  1. Static Analysis to Enhance the Power ofModel Checking for Concurrent SoftwareCarnegie Mellon University and the University of Wisconsin MURI, May 2001 Email: emc@cs.cmu.edu WWW: http://www-2.cs.cmu.edu/~modelcheck/onr/cip.htm Sept. 2004 MURI Objective • Develop tools to help software engineers reason about and understand whether a software system has a desired property, such as safety, security, or service guarantees • Provide diagnostic capabilities – in particular, counterexamples produced automatically from refutations ONR University Research Initiative Topic #9: “Objective: To understand, express, and effectively reason about software and quality. ” • Scientific/Technical Approaches • Model checking – verify the behavior of a software system by means of state-space exploration • Tunable methods for abstractions of a transition system: 3-valued structures, predicate abstraction, etc. • Iterative refinement – the property to be verified guides the search • Automated theorem proving using decision procedures based on Boolean satisfiability • DoD Capabilities • Classes of DoD systems for which this research is especially relevant • Embedded systems: airplanes, vehicles, communication systems, etc. • Concurrent systems: multiple threads executing simultaneously • Legacy code, COTS (commercial-off-the-shelf) software, and low-level code
