A Fast Component Modeling Implementation Method Based On VPL

In order to implement the manufacturability examining of avionics modules, an automated DFM software platform is constructed based on Valor combining the features and technological requirements of avionics modules. As an indispensable part of the automated DFM software platform, coverage area and data accuracy of component model library are important for the result of manufacturability examining. The constructing necessity, constructing course and technological requirements of the component model library are presented, and an efficient modeling method is introduced for components based on Valor VPL. The results show the method introduced is efficient, and the precision of component models modeled by this method is adequate for manufacturability examining, which makes it possible to construct large-scale component model library.
