Methods for classifying and correlating simulation components to functional models. A method includes receiving a simulation component library comprising a plurality of simulation components into a memory of the data processing system, parsing the plurality of simulation components from the simulation component library, analyzing a plurality of extracted functions into a plurality of function graphs for each of the plurality of simulation components, composing an extracted functions graph with the plurality of extracted functions of the plurality of function graphs, and storing the extracted functions graph of the plurality of extracted functions in a components-to-function database.
