1. 两个cell合并到一个gds
calibredrv -shell
layout filemerge -in A.gds -in B.gds -out AB.gds -createtop AB_TOP
也可以不加createtop，这样A，B就是平级的。
2. 很多cell
calibredrv -shell
layout filemerge -in A.gds -indir gdsdir/ -out TOP.gds
calibredrv合并GDS需要的命令
layout filemerge -in input_file1 [layer_bump1]
[-in input_file2 [layer_bump2] …]
[-infile {
-name filename
[-layerbump layer_bump]
[[-exclude_layer {layer1 …}] |
[-include_layer {layer1 …}]]
} ] …
[-indir directory]
-out output_file
[-mode mode]
[-cblockmode [auto | 0 | 1]]
[-smartdiff [-ignoretext] [-ignoreproperty] [-convertpathtopoly]]
[-noemptycells 0 | 1]
[-createcache 0 | 1]
[-exclude_layer {layer1 …}] |
[-include_layer {layer1 …}]
[-createtop cellname]
[-topcell topcellname]
[-map_cell cellname mapcellname]
[-preserve filterfile]
[-tmp tmpdir]
[-verbose]
看起来很多option，其实通常用到-in和-out就够用
