Atomicity Decomposition Plug-in User Guide

Introduction

The Atomicity Decomposition (AD) plug-in allows an explicit representation of control flow and explicit representation of refinement relationships between an abstract event and the corresponding concrete events.

See the Atomicity Decomposition page for technical details.

Currently the AD diagrams can be defined in an EMF tree structure included in an Event-B machine which is opened by Rose editor. After defining the control flow and refinement relationships via AD diagrams, the AD diagrams can automatically transformed to the Event-B notation.
