In past years, formal verification techniques and tools were widely developed and used by the research community. However, the use of formal verification at industrial scale remains difficult, expensive and requires lot of time. This is due to the size and the complexity of manipulated models, but also, to the important gap between requirement models manipulated by different stackholders and formal models required by existing verification tools. This dissertation aims therefore to develop a methodology that define activities that fill this gap by generating formal artifacts from textual requirements and existing design models. Our approach is based on previous work on the exploitation of contexts for formal verification, particularly, CDL l...
