| Research Abstract |
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 procedures
The 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 procedures
The 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 system
Two 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.
