Example of a Parameter Box

The following sections explain the initial and current value

fields in the parameter box.

Initial value

The initial value field displays a single value

taken from the parameter specification that you set up either in

Schematics (using the OPTPARAM symbol) or in the PSpice

Optimizer (from the Edit menu, select Parameters).

Current value

Initially, the current value is taken from the

parameter specification you set up in either the schematic or the

PSpice Optimizer. With each iteration of an optimization, the

optimizer updates the current value field with the new set of

parameter values.
