Abstract

This paper presents a method of design automation for analog circuits, focusing on topology generation and quick performance evaluation. First we describe mechanisms to generate circuit topologies with hierarchical blocks. Those blocks are specialized by adding terminal information. The connection between blocks is in compliance with a set of synthesis rules, which are extracted from typical schematics in the literature. Symbolic analysis has been used to select an appropriate topology quickly and to help the designer gain a better understanding of a circuit's behavior. Finally, experimental results show the creativity and efficiency of our method.
