使用SMIC65nm工艺,在做完ICC的route之后,使用了verify_drc这条指令,查看了报告文件,出现了如下几种错误: Rule: Via7 MinContNum: fat contact ( 0.809 , 0.809 um) minimum number of contacts = 4 566084 errors

Rule: Via2 Spacing : minimum spacing = 0.11 um 4 errors 错误数量十分之多啊!!!!! 然后在eetop论坛里面查看解决方法,看到说可以使用以下两条指令: route_zrt_eco route_zrt_detail –incr true 但是我使用以上两条指令后的结果还是和上面的一样,没有什么作用。 然后使用 Error Browser 查看,可以看到错误所在的地方,却不知道怎么修改啊!!!!! 不知道各位在跑ICC的时候,在最后检查DRC的时候,使用verify_drc报出大量的错误,一般都是怎么样个步骤去解决的啊?????? |
