Title: Calibre LVS subckt ICV_1 ICV_2
Post by casual on Oct 15^th, 2010, 1:58am

I took a look on the Calibre LVS layout netlist. There is a unknown subckt names call ICV_1, ICV_2, ICV_3 etc... (the netllist is LVS clean).

Why I got such subckt name? I look into the subckt name, it is my decap transistors. Why the Calibre put the circcuit into subckt? Is it because I add those decap by "adding instance command i " rather than "generating from source command"

I did another experiment by adding more decap by i command. It is still passed even layout got more decap than my schematic. Is my LVS screw up??
