Example 27—Monte Carlo Analysis Autostop
Netlist file: monte_carlo_autostop.cir
This circuit illustrates the autostop feature of Monte Carlo analysis. Eldo can automatically stop
the MC simulation when a preset accuracy condition is met. This can be much more efficient
than setting an arbitrarily fixed number of runs. In this case we setup the analysis so that a
prescribed relative accuracy is reached for the standard deviation of the 3dB bandwidth of the
circuit (a simple opamp in follower mode). In this example, the process should stop after
approximately 800 samples.
