This paper provides a tutorial introduction to EVES. EVES is a formal methods tool consisting of a set theoretic-based language, called Verdi, and an automated deduction system, called NEVER. We provide a general introduction to EVES and demonstrate its capabilities using (i) some examples from set theory, (ii) a small critical application (a railroad crossing), and (iii) a small program proof. Keywords: Automated deduction, EVES, Formal methods, Logic of programs, NEVER, sVerdi, Verdi. 1 Introduction The primary goal of the EVES project was to develop a "verification system" by integrating techniques from automated deduction, mathematics, language design and formal methods, such that the resulting system is useful and sound. In our parlance, a verification system has a specification and implementation language (e.g., Verdi), a proof obligation generator, and automated deduction support (e.g., NEVER). 1 To understand our perspective, some background is necessary. We believe that th...
