how to merge GDS through icfb
I need to export the GDS of my digital part. However, the GDS exported through ICC doen't contains all the infos because of the incomplete Milkyway database. and now I wannamerge the GDS through GDS, could anyone give me some detailed instructions? the more specified, the better.
thanks in advance.
gds merging has several way :
1. use icfb ,first streamin all reference library gds , then streamin in top gds ,
choosereference lib (no merge) options when streamin , then streamout , ok
2. use -depth >20when streamout from icc,that is , merge all full gds layer
in all reference library to combined into full gds
3. use -merge from edi when streamOut , -merge all gds
4. use calibredrv , layoutMerge command , can do it ,
i always use 1) icfb to merge , which is traditional and not error prone ,
thank icfbicfb again.
hi icfbicfb,
I use the icfb to merge according to what you said. But the gds I write out has no the information of the layers.
Can you give me some advice?
maybesome files needed but you did not added，like techfile.tf or display.drf, or you have added, but did not attached it.
I know it. The option I set is wrong, and my techfile.tf also has some problems. Thanks.
I have meet some problems when I stream in the top gds to reference full gds. The stand cells in top gds have covered the same cells in reference lib, so that the merge is failed. I think it is my mistake, but how?
你可以说中文来描述问题
learning ！
小编，想请教，具体用icfb merge GDS的脚本流程。我现在是如下做的：1. 用xstream将cell、io的gds都stream in，再将top的gds stream in，再将dummy metal和dummy poly的gds stream in。
2. stream out出gds。但生成的gds，并没有将dummy给merge进去。
想问问， 在stream的时候，要开哪些参数么?小编说的“choosereference lib (no merge) options”，用xstream脚本的话，是设置哪个参数?
后面的为什么跟风用英语，看着蛋疼。
