摘要
A CAD tool for analog circuit synthesis is presented. This tool, called FASY, uses fuzzy-logic based reasoning to select one topology among a fixed set of alternatives. For the selected topology, a two-phase optimizer sizes all elements to satisfy the performance constraints minimizing a cost function. In FASY, the decision rules used in the topology selection process are introduced by an expert designer or automatically generated by means of a learning process that uses the optimizer mentioned above. The capability of learning topology selection rules by experience, is unique in FASY. Practical examples demonstrate the tool ability of this tool to learn topology selection rules and to synthesize analog cells with different circuit topologies.

提出了一种用于模拟电路合成的CAD工具。这个名为FASY的工具使用基于模糊逻辑的推理在一组固定的备选方案中选择一个拓扑。对于选定的拓扑，两阶段优化器会调整所有元素的大小，以满足最小化成本函数的性能约束。在FASY中，拓扑选择过程中使用的决策规则由专家设计者引入，或者通过使用上述优化器的学习过程自动生成。通过经验学习拓扑选择规则的能力在FASY中是独一无二的。实际示例演示了该工具学习拓扑选择规则和合成具有不同电路拓扑的模拟单元的工具能力。
