A system for analog circuit design that stores and re-uses design procedures

A novel methodology for effective design of analog circuits is presented. While a conventional design environment stores and re-uses designed circuits, the proposed methodology stores a design method that is developed by a designer in his design process, and reuses it for automatic design. In order to evaluate for methodology, an interactive design system called GUIDE has been developed. GUIDE provides a convenient design environment for a designer and automatically stores a design procedure taken in his design process. GUIDE also designs the circuit automatically by reusing the procedure under different sets of specifications and process parameters, which leads to high design efficiency. The effectiveness of the system is demonstrated by experimental results.
