Is it possible to create gds of a design for which some subcells are included and others are not? For instance, some of my subcells are vendor macros, for which I need to stream an empty reference like with "Translation Depth"=0. But other instances are part of my custom design so I need them to be included. I considered first flattening those instances into the top level, but this is undersirable because of hierarchical reuse. Is there any sort of cell list parameter that can do this?
The content of cells from a Reference Library are not streamed out, just the instance information, so you could just put the library these cells come from in the Reference Library list for Stream Out (Stream Out Options, Libraries, Reference Libraries).
Hopefully this helps?
