Stability analysis

007_monte-carlo_simple_op : Stability analysis

Requires: SmartSpice & Smartview

Minimum Versions: SMARTSPICE 3.17.26.C

This example input deck shows new .DCOP syntax: .dcop monte=val prmc <donotprintop>

Statement: .OP MONTE=3 prmc donotprintop

In this case, SMARTSPICE will perform a DC OP analysis with Monte Carlo steps = 3.

Output:

MONTE CARLO STEP #1
