@Tim Edwards and/or @David Lindley: We would like to keep our openlane macros (Tiny Tapeout user submissions) in the shuttle repo as .oas instead of .gds to save some space. Can we assume that a .gds -> .oas -> .gds conversion doesn't break anything? I did a XOR check with ~100 previous submissions and it found no differences but we would like to be extra sure. (We are using klayout's `strm2oas`/`strm2gds` for conversion if that matters.)

Hi @htamas. I have had no issues converting back and forth GDSII - OAS. If you are concerned you should start a fresh klayout session, load both layouts, then XOR them. That's a fairly quick exercise. Make sure to select the klayout compression routines if you want to maximize your OAS disk savings.

Thanks!
