In this article we would like to present some recent applications of the B formal method to the development of safety critical system. These SIL3/SIL4 compliant systems have their functional specification based on a formal model. This model has been proved, guaranteeing a correct by construction behaviour of the system in absence of failure of its components. The constructive process used during system specification and design leads to a high quality system which has been qualified by French authorities.
