import a GDS file into virtuoso

Graphene1

Hi all, 

As part of my final project in Micro electronic devices, i would like to open a GDS file in virtuoso . I was trying to do the following steps: 

1. create new library

2. in that library -  File->import->Stream

In the  end of that process I couldnt find any new layout to open.

Does anyone has an idea?

Thanks!

  • Taking a stream file (aka GDSII) and importing it and then being able to export DEF is far from trivial. You might be able to do it if you can get Virtuoso Layout Suite XL to recognize the layout devices and match against a source schematic - there's some new options in IC616 VLS XL which will help with that (Update Binding) - but even then I think it's quite a tough challenge.

    Why do you want to do this? Stream format has no connectivity information, so it's not really the best format if you want to represent logical connectivity...
