Event-B is a formal method used for specifying and reasoning about systems. Rodin is a toolset for developing system models in Event-B. Our experiment which is outlined in this paper is aimed at applying Event-B and Rodin to a flash-based filestore. Refinement is a useful mechanism that allows developers to sharpen models step by step. Two uses of refinement, feature augmentation and structural refinement, were employed in our development. Event decomposition and machine decomposition are structural refinement techniques on which we focus in this work. We present an outline of a verified refinement chain for the flash filestore. We also outline evidence of the applicability of the method and tool together with some guidelines. © 2009 Springer-Verlag Berlin Heidelberg.
