Streaming and merging two gds files

Hello sclemow,

Below you can find the SKILL script to merge to cells.

You will need to modify the parameters , cell names, library names etc according to your requirements. I have marked these the code with <> statements.

1. First it streams in the GDS1.gds and GDS2.gds files into LIBRARY1 and LIBRARY2.
2. Then, it creates a new library NEW_MERGED_LIBRARY, creates a new cell and instantiates LIBRARY1 and LIBRARY2 top cells within this cell. Then, it streams out the merged cell.

Hope this helps. ;-)
