Synthesis and design automation of analog fuzzy logic VLSI circuits

A mathematical synthesis of current-mirror-based VLSI circuits suitable for design automation is proposed. In particular, a unified approach to synthesizing analog, current-mode CMOS fuzzy logic circuits is presented. The mathematical approach used for the fuzzy logic function synthesis is suitable for synthesis and design automation purposes. The approach is implemented in a prototype framework for automated synthesis and layout generation. By utilizing the existing software packages, VEE-Test and GDT Designer, efficiency, portability and compatibility are obtained. The advantage of the system over the classic design approach is demonstrated by the design of the fuzzy membership function circuit and the fuzzy logic controller circuit.<
