monte carlo mentor 2008

Hi

Does anyone have a basic and practical tutorial to perform monte carlo analysis using mentor graphics tools???? I need to estimate the random offset in an opamp, and any suggestion about it will be very useful to me.
Thanks a lot!!!!

Filipe

Hi,
please find below a small example :

*Non-Inverting Amplifier
.param voffset=0.1 lot=50%
r1 5 3 100k
r2 5 0 1k
c1 3 0 1p
yopa opamp2 pin : 2 5 3 0 param: p1=1e3 p2=5e8 gain=5000 voff=voffset
vin1 2 0 sin (0 1 100)
.tran 0 50m
.mc 7
.plot tran v(2) v(3)
.option display_carlo
.end
