求助DRC error

时间:10-02 整理:3721RD 点击:
各位大侠,我用的0.18um工艺,在做calibre DRC的时候出现了下面这么多error,请教一下该如何修改,谢谢!
有一些是因为desity不够,可以在所报区域加上一些dummy来解决;我很疑惑的是,为什么encounter布局布线,还会有Metal间距的问题(第29个)和Metal宽度的问题(第25个)?其它的错误都要解决吗?谢谢指教!

29.Spacebetween two Mn-1 regions is >= 0.28um


30.Minimumspace between Mn-1 lines with one or both metal line width and length aregreater than 10um is 0.60um

those with Mn-1 density less than 30%


34.Minimumspace between Mn-1 lines with one or both metal line width and length aregreater than 10um is 0.60um


35.Theminimum space must be maintained between a metal line and a small piece ofmetal(<10) that is connected


to the wide metal within 1.0um range from the widemetal.


36.Mn-1density is >= 30%. Dummy pattern is required for


those with Mn-1 density less than 30%

38.(Thisis for M4/M5/M6 stack)


39.Minimumspace between a small metal island and a big metal block is 1.00um.(small metalisland: width*length < 1um*um

seal ring. (AA, GT, CT, Mn, Vn, TM are OPC treatmentlayers) is >= 1.1um.


42.PMOSin PW is not allowed


没加filler吧,感觉,你列的error太多了,没人会帮你看的
首先edi里面要verifygeometry,verifyconnectivity过,

verifygeometry,verifyconnectivity确实有问题,有Antenna(Dangling Wire),open, spacing,short的问题,为什么会有这些问题呢?如下图所示,该如何着手解决Antenna(Dangling Wire),spacing的问题呢?谢谢!


这个要有人在旁边和你说才行,讲不清,

请问这个需要手动修改还是可以在encounter里面选择一些选项就可以解决?以前流片从来不会遇到这种情况,一般encounter的时候就没有Connectivity和Geometry的问题。谢谢!
