ICV cells in LVS

Hi,

 

During calibre top level extraction a cell called ABC is extracted as hcell. Now when I browse the netlist i found out that this cell is now part of an ICV_n Cell. And I see that ICV_n cell is instantiated in the TOP subcircuit and not cell ABC.

 

.subckt ABC a b c

...

...

.Ends

 

.subckt ICV_n 1 2 3

X0 1 2 3 ABC

.Ends

 

.Subckt Top x y z p q r s

..

..

X9 p q s ICV_n

...

..

.Ends

 

In the LVS report I see some net/device issue for cell ABC at cell level but when I browse the report for ABC instances at top level I don't see any information for these instances in the report. ABC is instantiated 5 times in the top level GDS.

 

I at least expected that I see ICV_n instances at top level report but I didn't find any! Is there a setup or known issue?

 

Best Regards,

Satish
