Exporting GDS

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

In the new window that opens up, specify a stream file.

Select the technology library (NCSU_techlib_tsmc02d).

Select YOUR library, top level cell and "layout" as the view.

Click on "Options".

Click on the "Layers" tab.

Click on "Load File".

Load this file of layer information: /mada/software/techfiles/NCSU_CDK_1.5.1/pipo/streamInLayermap

Alternative: Click on "Load Hierachy". NOTE: I'm not sure this is really needed...

Click on "Translate".

Turn in the GDS file. TELL ME WHAT THE TOP LEVEL CELL IS.

You can check that your file exported correctly by: 1) creating a new library, do a File->Import->Stream... 3) specifying the correct "top level" cell to translate. Another check is that the summary of objects is the same:
