To export GDS, you can go to File->Export->Stream... in the CIW.

In the new window that opens up, specify a stream file (for example, mult.gds). Select the technology library (NCSU_techlib_tsmc02d). Select YOUR library, top level cell and "layout" as the view.

Click on "Options". The first page should show an option "Translate Entire Hier". Check that or else it will only have shapes at the top level!

Now you need to set up the layer map. Click on the "Layers" tab. Click on "Load File" and select /mada/software/techfiles/ncsu/pipo/streamInLayermap. Click on OK.

Click on "Translate". You will see 8 ERRORs about "Failed to create the new layer purpose pair...", but we are not using those layers so it is ok.

Turn in the GDS file. NAME THE FILE THE SAME AS YOUR TOP LEVEL CELL OR I CANNOT OPEN IT!! If your top design is "mult" name it mult.gds. Case matter.


You can check that your file exported correctly by: 1) creating a new library but do not attach a technolgoy file 2) File->Import->Stream... 3) specifying the correct "top level" cell to translate. 4) specify the same layer map. 5) Verify your layout by opening the new layout in the new library.
