• Hi Matthias, You are correct. I reviewed the oasis case again and found the polygons in this case are same. So oasis use displacement record to compress it. I think it's efficient to represent multiple shapes as oasis. So I have another question. …

• Hi tlima, Thanks for your suggestion. In my case, the top name of tile gds is unknown, so I have to read it first to scan top name. Also, it's name maybe confict with cell name in main chip. This is why I need 'import other file' function, which c…

• Hi Matthias, I tried your suggestion, Do the operation first on all files while writing temporary files (2000 read + 2000 OASIS writes). Then read again and combine the layouts in non-editable mode. For step 2, I open layout in editable mode, then…

• Hi Matthias, Thanks for your reply. We use old linux (centos 4.6) with file version 4.10, which could not detect OASIS. However, I add API for klayout to report file type before reading the stream. extern std::string stream_format(const std::str…
