    compare m factor for the mos devices.

    victor_2017

      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.
