Title: preserivng schematic & layout connectivity information when copying cells
Post by ic_engr on Jul 30^th, 2013, 4:10pm

Hello,

In Virtuoso 5.1.41, I am using virtuoso XL. For archiving purposes I am copying the library with cells into a new library. What I note, is that in the destination library, the connectivity information between Source, & layout view remains for the origin and does not automatically change to destination lib. This is painful as one needs to go through every cell and update connectivity source library name.

Similarly, if the cell is copied or renamed, the XL connectivity information is lost.
Any help will be appreciated.

Regards
ic_engr

Not heard yet.
Now there is an option to do update on connectivity of source hierarchical.
But if then I re-name the cell the connectivity information is not updated to new cell name.

You should use the "Update" checkbox that is on either rename or copy from the library manager. This is assuming that you're using Cadence's library manager, and not an alternative library manager as provided by (say) a design management interface.

It's not really updating the "connectivity", but updating the references to the cellViews so that they end up pointing at the destination copies or renamed cells, rather than the original cellViews.

Kind Regards,

Andrew.
