摘要
本文介绍了LSIS-II布图设计系统结合规模生产的要求所进行的实用化设计和发展工作.包括系统采用的功能流、自检流、容错流的结构设计,单层金属布线工艺条件下的高密度布线设计,复合目标组合迭代布局优化设计,多种图形接口和系统稳定性的提高等.该系统已投入规模生产中的实际应用,已设计成功一批实际应用电路,其中包括1000门用户电路(已批量生产55万片)、单片集成度为38k、35k晶体管和8000逻辑等价门的应用电路.
The practical design for LSIS-II layout system in actual production is introduced,in-cluding the structure design with flow-function,flow-self-checking and flow-fault-tolerant,therouting design with high density on singl metal,and the multiobjective iteractive optimizationof placement as well as many kinds graphic interfaces.In order to increase the stability ofthe system, some experiments in harsh conditions were done,and the results are given.A Se-ries of circuits were designed successfully by this system.For example,the output of circuitof 1000 gates is 500 thousands in 5μn CMOS technology.
