项目摘要

We have developed an efficient design method for Analog LSIs that utilizes design procedures which are automatically acquired from a design process of a designer. We have applied the design methodology to circuit design and layout design of analog LSIs, and verified the effectiveness experimentally.Our achievements are summarized as follows.1.Development of a circuit design method that acquires and reuses design procedures.We have developed IDL (Interactive Design Language) for describing design procedures. The procedure can be reused for automatic design.2.Development of a layout design method that acquires and reuses design proceduresThe design procedure operated by a designer is stored. It is augmented with information required for generalization. Resulting procedure can be reused for generating layout under different set of parameters.3.Development of a prototype design system GUIDE that store and reuses design proceduresThe above two methods have been implemented into a prototype design system GUIDE.GUIDE system provide an interactive design environment for a designer. When he completes his desigh, his design procedure is captured in the form of IDL.It can be reused for automatic design.4.Application of the design systemTwo systems have been developed using GUIDE system. They are an automatic characterization system for LSI Libraries and a parameter extraction system of MOSFET models. Both systems are verified to be effective through the use in the development of actual LSIs.

我们已经开发了一种有效的设计方法，模拟LSI，利用设计过程中自动获得的设计程序的设计师。本文将该设计方法应用于模拟LSI的电路设计和版图设计中，并通过实验验证了其有效性，主要研究成果如下：1.开发了一种获取和重用设计过程的电路设计方法，开发了描述设计过程的交互式设计语言IDL（Interactive Design Language）。2.开发一种获取和重用设计过程的布局设计方法存储设计者操作的设计过程。它增加了泛化所需的信息。3.开发了一个存储和重用设计过程的原型设计系统GUIDE以上两种方法已在原型设计系统GUIDE中实现，GUIDE系统为设计人员提供了一个交互式的设计环境。在设计完成后，将设计过程以IDL的形式捕获下来，可供自动设计重用。4.设计系统的应用利用GUIDE系统开发了两个系统。它们是LSI库的自动表征系统和MOSFET模型的参数提取系统。这两个系统被验证是有效的，通过使用在实际的LSI的发展。
