Sensitivity Parameter Sweep

The Sensitivity parameter sweep is a type of parameter sweep which may be added as a variable entry in a Sweep Set in the Sweeps page of the Circut Settings dialog box. A Sensitivity parameter sweep is pictured below followed by definitions of the control fields.

A Sensitivity Sweep allows you to see how “sensitive” your circuit is to changes in any given variable. The nominal value of each variable is combined with the maximum and minimum values of the other variables as well as the nominal values.

In the example above,the combinations are nominal/min (200,180), nominal/max (200,220), nominal/nominal (200,200), min/nominal (180,200), and max/nominal (220, 200). The circuit is analyzed at each of these five combinations of variable values at each specified analysis frequency.

The table below shows the possible values of the two variables for this sweep set and all combinations. For a sensitivity parameter sweep for both Lstub and Sstub, the combinations at which the circuit is analyzed are highlighted in blue in the table below.

For a sensitivity sweep, the number of combinations which are analyzed is

where Nc is the number of combinations and Nv is the number of independent variables selected for the parameter sweep.
