I placed one of the vendor supplied subcircuits in my schematic, and I want to see the SPICE listing for this subcircuit. How do I do this?
You need to get into Info mode. Go to the Options menu and click on Mode and then Info, or click on the icon that has a picture of the letter I. All you need to do now is to click on the subcircuit in the schematic. The library that contains the subcircuit will be loaded, and the actual subcircuit SPICE listing will be shown on the screen. This technique is also applicable to all other parts. Clicking on a macro will display the macro circuit or parameter call, and clicking on a primitive will display the Attribute dialog box or the model statement that the part uses.
A second method, which will only work for subcircuits and parts that use model statements, is to double click on the component in the schematic while in select mode. In the Attribute dialog box, there is a text field for subcircuits or fields for all of the parameters if the component uses a model statement.
