Hello,
I have developed my layout (GDSII) using two types of "standard cells".
A. The standard cells developed in our lab, (Standard cells 'A')
B. The commercial standard cells of a company. (Standard cells 'B')
I have got all the details (layout, abstract etc) of 'A'; but for 'B' i have only got the abstract model (LEF, verilog details).
With the help of abstract model, i am able to do all the placement and routing of my complete design in encounter.
The final GDS generated by encounter contains GDSII of 'A' but not of 'B'.
I am unable to perform LVS (Calibre LVS) on the complete design. The LVS does not extract any thing from the layout for each corresponding 'B' cell. I want that LVS should treat 'B' as black boxes and only confirm me their connections with other cells, and not their internal details. How should i tell Lvs to treat some cells as black boxes? Any other solution?
Waiting for a reply
