Optimal mapping of functions to architectures using model based design

Today networked systems are very complex.Growing system and performance requirements, limited hardware resources and additional constraints complicate their design.Formal and informal quantities and specifications depend the overall system behavior too.Model based engineering enables system analysis and performance estimation in early design steps.Which system function should be processed by which architecture as a special problem is focused in this paper.Therefore a specific component library forms the basis of virtual prototyping.The intrasystems variable level of detail allow a simulation on different abstraction levels.The resulting performance values as input for naturally-motivated algorithms are used for optimization of bin packing problem (mapping) and shortest path problem (communication).Two prototypically examples clarify the forced methodology.
