I'm having LVS problem with one of the IP block layout. The block is LVS cleaned at the customer's site.

But it's not LVS cleaned when I run it in my environment. It has multiple open nets. I looked at one of the

opened net error between M1 and M2, there is actually and physically a VIA1 connecting these 2 nets ...

. As I debug further, I see there are multiple warnings from Calibre form as follows:


I am not comfortable with these warnings... Is it the right cause for open net ?? since I think some of the

vias might be dropped out when Calibre is doing extraction translation ....

Appreciate your help,

Thanks a lot,
