DRACULA中做LVL

步骤：

像运行drc一样地先执行lvl1.com , 注意，产生的dat文件不要杀掉，然后在同一个文件夹下再运行lvl2.com，然后在virtuoso里做查看drc error一样查看2个layout的相异之处。

openbook里有例子。关键的几个命令字就是：export , import-layer , 和xor。

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

lvl1.com 内容如下：

*description
indisk = old.gds
primary = tapeout top cell name
system = gds2 cad graphic system
outlib = old
outdisk = old.out
keepdata = yes
*end

*input-layer
ppwell = 1
nnwell = 2

export ppwell
export nnwell

*end

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

lvl2.com 内容如下：

*description
indisk = new.gds
primary = tapeout top cell name
printfile = comp
outlib = compout
outdisk = comp.out
keepdata = yes
*end

*input-layer
ppwellb = 1
nnwellb = 2
import-layer ppwell
import-layer nnwell
*end

*operation
xor ppwell ppwellb err0 output pwell 1
xor nnwell nnwellb err1 output nwell 2
*end
