Using formal methods to validate C programs

Presents the CAVEAT project. The purpose of this project is to develop a tool designed to assist a user in the verification of C programs. Such a verification is required for safety applications in a pragmatic approach. The tool enables a user to verify the global or local properties of these applications. The context in which a property is to be verified is defined in terms of hypotheses. Most of the steps of the verification process, in particular the rewriting steps, are executed automatically. The proof process, however, may be partially interactive, and the interface therefore allows easy communication.<>
