Chapter 12 Monte Carlo and sensitivity/worst-case analyses

Waveform reports
For Monte Carlo analyses, there are five variations of the
output that you can specify in the Save data from text box
on the Monte Carlo dialog box. Options:
The * indicates that you can set the number of runs in the
runs text box.
Values for the output variables specified in the selected
analyses are saved to the simulation output file and data
file.
Note
Even a modest number of runs can produce large output files.
<none> No output is generated
All Forces all output to be generated
(including nominal run)
First* Generates output only during the first
n runs
Every* Generates output for every nth run
Runs(list)* Does specified analysis and generates
outputs only for the listed runs (up to
25 values can be specified in the list)

display can look more like a band than a
set of individual waveforms. This can be
useful for seeing the typical spread for a
particular output variable. As the number
of runs increases, the spread more closely
approximates the actual worst-case limits
for the circuit.
