摘　　要：提出了一种基于串扰延时查找表的静态时序分析方法.该方法首先由芯片版图提取出串扰线仿真电路,然后采用批处理仿真方式得到串扰延时库.之后采用串扰延时分析算法,通过算法自动计算出跳变时间差和负载,处理多攻击线等,最终基于串扰延时库的查找表法进行分析计算,得到精确的串扰延时值.实验结果表明,采用本文提出的基于串扰延时查找表的静态时序分析方法所留裕量在7.24%~37.70%之间,为业界可接受范围内.This paper proposes a static timing analysis method based on crosstalk delay lookup table.First,we extract crosstalk line simulation circuits from the chip layout and use batch mode simulation method to obtain crosstalk delay library.Then we use the crosstalk delay analysis algorithm to calculate the jump time difference,the load and handle multiple aggressor line and so on.Ultimately,we analysis and calculate the accurate crosstalk delay value based on crosstalk delay look-up table.Experimental results show that static timing analysis based on crosstalk delay lookup table retains margin which is between 7.24%—37.70%.This margin is within the acceptable range in the industry.
