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.
Have a look at the section "Device Count Comparison After Reduction" in the Calibre Verification User's Manual. Also, see LVS Spice Replicate Devices in the SVRF Manual.
