Example 7—Monte Carlo Analysis Basic
yopa opamp2 pin: 2 5 3 0 param: p1=1e3 p2=5e8 gain=5000

.ac dec 30 1.0 100meg

The above lines indicate that an AC analysis should be performed on the circuit within the
frequency range 1Hz to 100MHz with 30 steps per decade. 500 Monte Carlo simulation runs
are carried out.
.print ac vdb(3)
.plot ac vdb(3)(-40,60)
.plot ac vp(3) (0,-90)
.end
A dB/frequency plot of the voltage at node 3 is requested, together with a phase/frequency plot
at the same node.
The plotted output results on the voltage at node 3 contain nominal simulation results without
any change in the circuit values, together with highest and lowest deviation results over the
simulation runs.
Tip
For more information on Monte Carlo analysis, refer to “Monte Carlo Analysis” on
page 265.
