Abstract

A method is provided for constructing at least a functional model of a complex system including a plurality of components. The method includes constructing the functional model of the complex system, including a hierarchized set of modelled functional components. Each of the functional modelled components is an instance of an object class belonging to a specific set of object classes. The specific set of object classes includes a “Functional Router” class, representing an abstract model of a dummy router, which describes a set of interconnections between at least two modelled functional components, each instance of the “Functional Router” class being called a modelled functional router. The functional model of the system includes at least one functional modelled router.

         10 . The method of  claim 9 , wherein the method includes:
 distributed mapping of said functional model to said platform model, via distributed assignment of said at least one modelled functional router to said at least one modelled physical router, making it possible to obtain an architectural model of said complex system.   
     
     
         11 . The method of  claim 1 , wherein said complex system is a complex electronic system. 
     
     
         12 . The method of  claim 1  and further comprising:
