ReqV is a tool for formal consistency checking of requirements. The main goal of the tool is to provide an easy-to-use environment for the verification of requirements in Cyber-Physical Systems (CPS). Reqv takes as input a set of requirements expressed in a structured natural language, translates them in a formal language and it checks their inner consistency. In case of failure, ReqV can also extracts a minimal set of conflicting requirements to help designers in correcting the specification.
