SOFL formal specifications have been proved to be useful and expressive enough in describing functional requirements for software development. Based on SOFL formal specifications, many techniques have been proposed to provide us with effective solutions for software verification and validation. To support these techniques, a tool support for analysis of specifications is necessary. However, suc...

Tools and methods for the specification and design of computer systems are increasing in sophistication. Much current research and development is attempting to exploit this sophistication to improve the effectiveness of systems development practices. It is becoming feasible to offer much higher assurance than hitherto that systems meet critical requirements, e.g. concerning safety or security. ...

We present an authoring tool for publication and dissemination of formal theories certified by a proof assistant. We have used TeXmacs, a ”wysiwyg” editor for scientific documents which allows a connection with symbolic systems and we evaluate this tool on our formal developments certified using Coq.

This paper presents a Logic Tutor, a tool to support computer science students in their learning of logic, more specifically in their learning of formal proofs. The current tool is equipped with a deduction system for propositional logic. However its modular conception makes it easy to change to another logic. Preliminary evaluation shows that this tool has a high educational value, thanks, amo...

NLCertify is a software package for handling formal certification of nonlinear inequalities involving transcendental multivariate functions. The tool exploits sparse semialgebraic optimization techniques with approximation methods for transcendental functions, as well as formal features. Given a box and a transcendental multivariate function as input, NLCertify provides OCaml libraries that pro...

Proof assistants aid the user in proving mathematical theorems by taking care of low-level reasoning details. Their user interfaces often present proof information as text, which becomes increasingly difficult to comprehend as it grows in size. Panoptes is a software tool that enables users to explore graphical representations of the formal proofs produced by the imps Interactive Mathematical P...
