You first have to figure out what data format .sf is.
I'm unfortunately not aware of these .sf extension.

Cadence Virtuoso currently support two layout exchange
formats.

First, most common used in industry GDSII 'Graphic Data System' (File -> Import/Export -> Stream),
for further information have a look at Cadence Online Docu (cdsdoc)
Design Translators Reference, Appendix A Stream Format

Second CIF 'Caltech Intermediate Form' (File -> Import/Export -> CIF),
http://caltechcstr.library.caltech.edu/431/
which is more used for education on Universities because it is an ASCII format and you can hack it whether GDSII is binary.

Dear Andrew&Bernd,

I can just use import-->stream in with a default.tf supplied by Cadence to convert the .sf file into a layout library, but the layer names showed in the LSW is L1, L2..., how can I change this name from the LSW?


Thanks a lot

I think since DFII Version 5.0.33 there is an option
'Attach Techfile Of Library'
under the Stream In Form 'Options'.

So if you already have a proper Technology Library
with a defined Techfile you can fill in there the name
of these library.

You may need also a layer mapping table.

Check it out.

My way to transfer the *.sf from foundry into library is that :
(1)use import-->stream in to create a techfile aaa.tf from the *.sf, then layer names are L1, L2...L99, I modify only the layer names as Ndiff, Nplus, Nwell..
(2)use import-->stream in to create a library bbb from the *.sf and techfile aaa.tf.
(3)Open the bbb library top cell view, modify the display format of each layer in the LSW and save.

Is it correct?

And there is only one purpose definition P0, can it work?

the aaa.tf contains:
layerDefinitions()
techPurposes(
;( PurposeName          Purpose#  Abbreviation          )
( P0                      1      P0                      )
)
techLayerPurposePriorities()
techDisplays()
layerRules(
streamLayers(
;( Layer            streamNumber      dataType      translate      )
)


Have a nice days
