Abstract
The method and programmed realization for multi-layered RAMs system, based on optimization design towards integration CAD system, were studied in the article. The system was based on both an optimization engine on genetic algorithms, and reflection index was calculated by means of transmission-line or tracking calculation. The electromagnetic parameter database was realized by server software-MYSQL based on open source software. Therefore, under the open source software system, the intelligent system of calculating design and performance prediction towards multi-layered RAMs was created successfully. The optimization calculating of multi-generation towards multi-layered RAMs was carried out, and the ideal design results were gained. Finally, the evaluation both result and intelligent system were also given.
