考虑的啊,你啥工艺,tf的,
tf里面会写的, 就是 在metal那块
unitMaxHeightFromSub = 0.59
unitMinThickness = 0.18
unitNomThickness = 0.18
unitMaxThickness = 0.18
fatTblDimension = 5
fatTblThreshold = (0,0.201,0.421,1.501,4.501)
fatTblParallelLength = (0,0.381,0.421,1.501,4.501)
fatTblSpacing = (0.09,0.11,0.16,0.5,1.5,
0.11,0.11,0.16,0.5,1.5,
0.16,0.16,0.16,0.5,1.5,
0.5,0.5,0.5,0.5,1.5,
1.5,1.5,1.5,1.5,1.5)
minArea = 0.042
minEnclosedArea = 0.2
maxNumMinEdge = 1
这些就是width dependent spacing rule ,
如果是LEF header file,也有类似的东西,
一般来说width越宽, space会相应的增大rule,
连smic18都有
pattern = "blank"
pitch = 0.56
defaultWidth = 0.28
minWidth = 0.28
minSpacing = 0.28
fatWireThreshold = 10
fatThinMinSpacing = 0.6
fatFatMinSpacing = 0.6
就是 如果碰到大于10um的线, spacing为0.6um
一般是0.28um |
