Hierarchy LVS problem when using xcells to do hierarchical extraction

Question asked by jiaqi on Mar 10, 2019

Hi everyone,

 

I want to use hierarchical extraction for my design. I run LVS alone with hcells and it is right. But when I use the same hcells to run LVS in xRC, it turns out that my LVS is wrong. I set the hcells and xcells the same. And my pex.netlist is full of noxref.

 

I wonder: 1. How can I make the LVS clean? 2. How can I get the schematic name on my pex.netlist?

 

Thanks.
