I would like to edit the parameters of the models that I am using. How can I do this?
Enable Select mode by going under the Options menu to Mode and then clicking on Select. Double click on the component whose model that you would like to edit. Highlight the line in the Attribute dialog box that states MODEL=modelname. Click on the Edit command button. This will bring up all of the parameters of the model for editing.
A model may also appear in the text area. Hit CTRL+G to toggle back and forth between the text area and the schematic area. In the text area, the model may be edited just like any other text. Going to the Edit menu and clicking on Add Model Statements will place all of the model statements for the circuit into the text area.
