Corner Parameter Sweep

The Corner 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 Corner parameter sweep is pictured below followed by definitions of the control fields.

A corner sweep allows you to analyze the “extremes” of your variables by analyzing at all the combinations of the minimum and maximum values of the variables as well as at the nominal values. This allows you to see how your circuit varies over the data range of your variable.

 For example in the sweep set shown below, there are two variables, Lstub and Stub, each of which has three possible values: the minimum, 180, the maximum, 220 and the nominal, 200.

The table below shows the possible values of the two variables for this sweep set and all combinations. Blue fill in the table indicates that the combination is analyzed. For a Corner parameter sweep, the combinations would be min/min (180,180), max/min (220,180), min/max (180,220), max/max (220,200) and nominal/nominal (200,200). The circuit is analyzed at each of these five combinations of variable values at each specified analysis frequency.

For a corner 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.
