Hierarchical copy of top cell

Ueue

Dear all,

I have a problem performing a hierarchical copy of my top cell.

My top cell has a quite complex hierarchy coming from 4 different libraries and I would like to create one single library self-referenced.

However, when I try the copy, some of the cells are not correct (for example the schematic and symbol are copied, but not the layout view).

How is it possible? Is there a reason for that behaviour?

Thanks a lot,
Stefano

 

  • Hi Stefano

    In the cell copy form, did you ensure that "layout" is one of the views to be copied or did you enabled the "Copy all views" option?

  • Stefano,

    You probably need to give more details on exactly how you're setting up the copy...

  • Hi,

     

    1) In the window copy cell, I checked "Copy Hierarchical";

    2) In "Skip Libraries" I removed all the libraries with which I don't want to keep any reference in the new library (I left only the tech libraries, analogLib, etc..);

    3) "Exact Hierarchy" is not checked;

    4) "Copy All Views" is checked;

    5) "Update Instances": "Of Entire Library";

    6) "Add to category" is not checked.

     

    Thanks in advance.

  • Hi Stefano

    Your steps look good. I think it would be best to file a service request to your local Cadence support and request for a remote debugging session. By the way, if you are using an old version of Virtuoso, it would be good to first retry the problem using the latest version.

    Best regards
