  Formal modelling languages play a key role in the development of software
since they enable users to prove correctness of system properties. However,
there is still not a clear understanding on how to map a formal model to a
specific programming language. In order to propose a solution, this paper
presents a source-to-source mapping between Event- B models and Eiffel
programs, therefore enabling the proof of correctness of certain system
properties via Design-by-Contract (natively supported by Eiffel), while still
making use of all features of O-O programming.
