Using Automated Theorem Provers to Certify Auto-Generated Aerospace Software
Basin, David and Rusinowitch, Michael (eds.)
At Second International Joint Conference on Automated Reasoning (IJCAR 2004).
We describe a system for the automated certification of safety properties of NASA software. The system uses Hoare-style program verification technology to generate proof obligations which are then processed by an automated first-order theorem prover (ATP). For full automation, however, the obligations must be aggressively preprocessed and simplified.We discuss the unique requirements this application places on the ATPs and demonstrate how the individual simplification stages, which are implemented by rewriting, influence the ability of the ATPs to solve the proof tasks. Our results are based on 13 certification experiments that lead to more than 25,000 proof tasks which have each been attempted by Vampire, Spass, and e-setheo.
