Streaming out pcells to gds

mtwadeCU

Hi,

While I'm actively developing a pcell, it is useful to be able to stream out a gds directly from the pcell without instantiating it in another layout first. However, when I try to stream out the pcell using the CIW File -> Export -> Stream, the streamed out file is empty and the "Summary of Objects Translated" message to the CIW shows that zero shapes were translated. If I first create a new layout cellview and instantiate the pcell in that layout, I can stream things out just fine. Is there a way to stream out a pcell without first instantiating it in a larger layout? 

Thanks,

Mark

    Another clue: I found that streaming out without instantiating works on version 6.1.5. However, we can't use 6.1.5 due to its inability to handle size operations on polygons larger than 4000 points. The exact versions are: 

    IC6.1.5.500 (works)
    IC6.1.6.101 (does not work)

    As a workaround, we're using 6.1.5 for streaming out and 6.1.6 for our polygon operations, but it's kind of a pain.
