Abstract: A review of the progress in automated design of analog integrated filters is presented. Such tools are ahead of other analog circuit automation in terms of the acceptance by designers and practical applicability. A survey of the present-day commercial and academic systems is made and the range of facilities available is compared. The problems faced in the design of this type of software are typical of the problems of analog design systems in general; lack of openness for introduction of new design knowledge, difficulties of dealing simultaneously with expert and novice users, poor integration in design environments, and user-interface problems. The structure of a typical system is studied and the computer methods used within are discussed with regard to such issues as speed, flexibility, and ease-of-use. Some future directions for analog filter compilers are proposed.
