Use the Device Parameters node () to declare the inputs that the device model supports. Each device input also needs a default value. These inputs can be used in the equations of the device model. Right-click the Device Model node to add the Device Parameters subnode.

Fill the table with the parameters you need for a device model. A device instantiating a device model can modify the default values through the Input Modifier. As an alternative to specifying the parameters in this node, you can add them directly in the Device Parameters section of a Device Model. For valid entries in the Dimension column, see Variable Declaration.
