Working with Variables

Properties and quantities in Twin Builder may be represented by alphabetic or alphanumeric variables. For example, the capacitance property of a capacitor may be set to the value of the variable C1, rather than set to a numeric quantity, like 1.0uF. A property that has been set to a variable is said to be parameterized.

In some cases, the use of variables is mandatory. For example, if you want to sweep the current level of a source during analysis, you must set the current level equal to a variable, so the simulator can identify and vary the level as the solution proceeds.
