怎么flatten一个GDS所有层次[更正】

# Before:
# topcell -> a -> b -> c -> d
# topcell -> b -> c -> d
# topcell -> c -> d # After:
# topcell

下面的code保存为flatten.txt. 执行calibredrv flatten.txt

set lay [layout create "abcd.gds" -dt_expand \
-preservePaths -preserveTextAttributes]
set topcell [$lay topcell]
$lay flatten cell $topcell
$lay gdsout out.gds

最近用到发现上面的不能flatten reference, 更新如下

 # Before:
# topcell -> a -> b -> c -> d
# topcell -> b -> c -> d
# topcell -> c -> d
set L [layout create "abcd.gds" -dt_expand \
-preservePaths -preserveTextAttributes]
layout copy $L newL
newL gdsout abcd_flatten.gds
# After:
# topcell
