Use to bypass the “intelligent” system (F7) used for regular editing of a component’s Spice value. This option allows you to type in any text string for the value.

For example, use it to enter a device parameter expression for a resistor value. e.g. “{res}“. This could then be used in parameter stepping using Multi-Step Analysis.

How To Enter Spice Value Text

Select the required component(s) and press Shift + F7. The following dialog will be displayed:

Type in the required expression for the Spice value.

Note: If you subsequently use F7 on the component after setting up the expression, the value will revert to the correct type for that device. e.g. a numerical value for a resistor.

See “Using Expressions for Circuit Parameters” section in the Simulator’s Users Guide Manual for more details on using parameters.
