1. A hierarchical adaptive system for emulating a process of designing integrated circuits and printed circuit boards comprising a tool manager, a schematic parser, a pseudo placement engine, a pseudo router, an electromagnetic translator, a schematic back annotator, and a shared information database, whereina) said tool manager supervises and controls the storage and transfer of data,b) said schematic parser translates an electrical design schematic into a connectivity matrix wherein said electrical design schematic identifies components, properties of said components, pin connections and electrical interconnections,c) said pseudo placement section comprising fuzzy neural network determines routing channels, component size and placement using input data from said schematic parser, said tool manager, and said shared information database,d) said pseudo router section comprising fuzzy neural network generates a pin-to-pin routing,e) said electromagnetic translator section determines electromagnetic parameters from said routing channels, said component size and placement and said pin-to-pin routing,f) said schematic back annotator updates said electrical design schematic with said electromagnetic parameters, andg) said shared information database is accessible by said pseudo router, said pseudo placement section and said electromagnetic translator, and contains integrated circuit manufacturing and design data.
