Rodin tool
The Rodin tool is a tool for formal modelling in Event-B. Event-B is a notation and method developed from the B-Method and is intended to be used with an incremental style of modelling. The idea of incremental modelling has been taken from programming: modern programming languages come with integrated development environment that make it easy to modify and improve programs. The Rodin tool provides such an environment for Event-B. The two main characteristics of the Rodin tool are its ease of use and its extensibility. The tool focuses on modelling. It is easy to  modify models and try out variations of a model. The tool can also be extended easily. This makes it possible to adapt the tool to specific needs, so the tool can be adapted to fit into existing development processes instead of demanding the opposite. The Event-B wiki is a useful user and developer resource. Rodin (Rigorous Open Development Environment for Complex Systems) is an extension of Eclipse IDE (Java based). Rodin Eclipse Builder coordinates: Industrial applications and case studies. The Rodin project included five industrial case studies that served to validate the tool set and helped with the elaboration  of an appropriate methodology for using the tools. The case studies were led by industrial partners of the Rodin project supported by the other partners. The case studies were as follows:
