    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
