Rodin tool

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. Two characteristics of the Rodin tool are its ease of use and its extensibility.

The tool focuses on modelling. It allows the user to modify models and try out variations of a model. The tool is also extensible. 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. There is an associated Event-B wiki.{{cite web| url=http://wiki.event-b.org/ | title=Event-B and Rodin Documentation Wiki | website=wiki.event-b.org | accessdate=13 June 2023 }}

Rodin ("Rigorous Open Development Environment for Complex Systems") is an extension of Eclipse IDE (Java-based). The Rodin Eclipse Builder manages the following:{{cite web| first=Michael | last=Butler | author-link=Michael Butler (computer scientist) | url=https://www.southampton.ac.uk/~mbutler/rodin.pdf | title=RODIN – the next generation refinement tools | publisher=University of Southampton | location=UK | accessdate=13 June 2023 }}

• Well-formedness and type checker
• Proof obligation (PO) generator
• Proof manager (PM)
• Propagation of changes

;Rodin Proof Manager (PM)

• PM constructs a proof tree for each PO
• Automatic and interactive modes
• PM manages used hypotheses
• PM calls reasoners to:
• discharge goal, or
• split goal into subgoals
• Collection of reasoners:
• simplifier, rule‐based, decision procedures,
• Basic tactics language to define PM and reasoners

The Rodin project included five industrial case studies that served to validate the toolset and helped with the elaboration of an appropriate methodology for using the tools.{{cite web| url=http://rodin.cs.ncl.ac.uk/D34.pdf | title=Project IST-511599 RODIN “Rigorous Open Development Environment for Complex Systems” | publisher=Newcastle University | location=UK | accessdate=13 June 2023 }} The case studies were led by industrial partners of the Rodin project, supported by the other partners. The case studies were as follows:

• A failure management system for an engine controller;
• Part of a platform for mobile Internet technology;
• Engineering of communications protocols;
• An air-traffic display system;
• An ambient campus application.
