Your question is pretty unclear, but did you try using the flatten command in
the Virtuoso Layout Editor?

Hi Andrew

I have tried the way
This method is too slow
I want to use the procedure to fast flat
Could you help me?

I don't understand what you're asking (perhaps because of your English?). Why do
you want to flatten the layout anyway? It would only be slow if you have a very
large amount of data to be flattened, and usually there should not be a need to
do that.

Regards,

Andrew.

 

The labels can get lost in different stages of the process

Calbire requires a stream out to GDSII format and then
processes GDSII.

- Have you checked if your GDSII layout database still
contains the label/text layer.
You can do that in using a GDSII viewer like calibredrv or
streaming back the data into Cadence DFII.

If not, maybe the label/text layer is not defined in the stream out
mapping table or your DFII library tech file.

- Calibre itself needs a command rule file to process your
GDSII layout database maybe the label/text layer is not mentioned in
there.
You have to check if your label/text layer is covered in there
There must be a mapping, similar to that below

LAYER myTextLayer 11
LAYER MAP 11 DATATYPE 0 110


But it would be very helpful if you could be more specific what your
exactly trying to do and if you would describe your steps more detailed.

PS: I'm a friend of short question leading exactly to the point,
but your post is definitely not to understand.

 

Hi, All:

Sorry for my poor English in previous post. Let me clear my question
here.

I like to flatten top cell and keep labels. But, I don't want to do
this by GUI.
Is there any way I can do this in batch mode? The GUI takes too much
time for
parsing and showing the whole stuff.
Another question! When I'm using Calibre to flatten the layout, all
label/text
disappeared. How can I recover the label and text?

Any suggestion are welcome.

Sincerely yours,
Connie
