Variables
The Variables page is opened when you select "Variables" in the side bar menu of the Circuit Settings dialog box which allows you to create and edit all the variables in your circuit at once. Each variable has a text entry box for its name and for its present value or defining equation.
Add: Clicking on the Add button opens the Add/Edit Variable dialog box which allows you to define a new variable. When that dialog box is closed, the new variable is added to the list above.
Edit: Clicking on the Edit button opens the Add/Edit Variable dialog box with the properties of the presently selected variable. You may also open the dialog box by double-clicking on a variable entry. When that dialog box is closed, the variable's listing is updated with the changes entered.
You may directly edit the displayed properties of the variable in this dialog box without opening the Edit Variable dialog box.
Move Up: Click on this button to change the position of the presently selected variable in the list. The variable is moved up one position each time you select the button.
Move Down: Click on this button to change the position of the presently selected variable in the list. The variable is moved down one position each time you select the button.
Delete: Clicking on the Delete button removes the presently selected variable. This action is not permitted if this variable is presently being used in an equation or referenced in your circuit.
Selecting Circuit ⇒ Variable List opens the Variable List dialog box which allows you to create and edit variables for your netlist project.
Click on the New button to add a new variable. Two text entry boxes; one for the variable name and the other for the nominal value. Enter the desired name for the new variable in the Variable text entry box and the desired nominal value in the Nominal Value text entry box. Once these variables are created, you may use them to define the value of modeled elements in your netlist, such as resistors, capacitors, inductors and transmission lines. In other words, the modeled element uses the present nominal value of the variable for the netlist analysis. This dialog box allows you to change the value of all your variables at once rather then having to edit each modeled element entry in your netlist.
Creating variables allows you to perform an parameter sweep or optimization on your netlist.
If you wish to remove a variable, click in one of the text entry boxes for that variable, then click on the delete button.
