Actually the block  LVS is clean, but I want to check number of 'm' factors for the mos devices  in the LVS.
I try to using 'TRACE PROPERTY MN(N) m m 0'
It is partially working, if the drawn layout device's m==1, and schematic(netlist)'s m > 1 then it could be checking normally.
but if the drawn layout device's m > 1 then I can see following message.
   M8 (1.1 1.1) MN(N)                       MMN1q   MN(N)
   m : ? (reduced inatsnce)                m: 2

 

I think Calibre can't extract mos device 'm' property from layout.
How can I do it for m factor checking?

I'm using reduce option.
   - LVS REDUCE PARALLEL MOS YES
   - LVS REDUCE SPILIT GATES  NO

Please let me get any help.
