How to export GDS using terminal

Muralidhar

Hi,

I want to export GDS from the given layout. I know that it can be done by using Virtuoso CIW like File-->Export-->streamOut and giving the required fields. But I want to do it using terminal (linux commands). I have seen that it can be done using strmout command but I don't know how to do it. Please tell me how to use it. If possible give an example.

Thanks,

Parents

  • strmout -library <libName> -topCell <cellName> -view <layout|viewName> -strmFile <outputGDSFile> -logFile strmout.log

    There are many options so you may need to adjust the command accordingly.  You could try reading the documentation?  You didn't say which version you are using, which is important information. Here's an example of "strmout -help":
