PSpice - Tip of the Week: Using Expressions to Define Model Parameters

Now, you can use expressions instead of values in the Modeling Application (Place > PSpice Component > Modeling Application). For example, instead of supplying a fixed voltage for the Initial Condition (IC) of a capacitor or an inductor, you can now use an expression to track a testbench parameter.

In addition to the IC, you can also use expressions for Parasitic Resistive Element, Temperature Coefficient, and Voltage or Current Coefficient values.

In the following example, two expressions, SS*2 and ESR, are used to define the initial condition and series resistance, respectively, for a capacitor. The two parameters are defined using the PARAMETERS table.
