Current literature provides many studies on the mechatronic design process. However, they
only focus on one level of the design V-cycle. This study deals with the entire downward
side of the cycle in view to processing it globally. To achieve this, we propose a hybrid
methodology based on several tools, languages and methodologies such as SADT, SysML,
Modelica and CATIA Systems®. The method was validated successfully in a
Modelica/Dymola framework. It is now possible to partially automate the process.
