I would like to edit the parameters of the models that I am using. How can I do this?
Enable Select mode. Double click on the component whose model you would like to edit. Highlight the line in the Attribute dialog box that states MODEL=modelname. The MODEL attribute must be defined. Once this attribute is highlighted and defined, all of the parameter fields will be active at the bottom of the dialog box and available for editing.
A model may also appear in the text area of the schematic. In the text area, the model may be edited just like any other text. Going to the Edit menu and clicking on Refresh Models will give you the option to place all of the model statements for the circuit into the text area.
