摘要

介绍了一种按需生成库的专用集成电路定制设计方法。根据性能评估的结果，生成一个定制的库，并提供给基于单元的设计工具。开发了一种可产生可变驱动强度单元格布局的符号布局系统。利用这种可调性可以产生丰富的驱动强度集，并在布局后阶段进行设计优化。设计实验和成品芯片的测试性能证明了该方法的有效性。

ASIC design methodology with on-demand library generation

This paper describes a custom design method of ASICs with on-demand library generation. According to the result of performance estimation, a tailored library is generated and supplied to cell-based design tools. A symbolic layout system that produces a cell layout with variable driving strength is developed. The tunability can be utilized for generating a rich set of driving strength as well as design optimization in post-layout stage. Design experiments and measured performance of a fabricated chip demonstrate the effectiveness of the proposed approach.
