Hello,
I have circuit in CADENCE, in which I use a cmos inverter with 5 finger for pmos and 4 finger for nmos. I have another PMOS in the same design with 10 fingers. When I do the LVS, it fails because it can not relate the inverter in the layout to the inverter in the schematic. and says the instance is missing in schematic.(Although the stand alone PMOS is being mapped correctly) when I check the Extracted schematic from the layout it matches the original schematic. Also the transient waveforms for the circuit are correct.
One more thing I would like to add that in the schematic extracted from layout, A transistor of say W = 10um with 10 fingers is shown as 10 parallel transistor with W = 1um each.
So my question how to tell LVS that these transistor in the layout are mapped to which ones in the schematic
