To find out more about PSpice command and netlist syntax, refer to the online PSpice Reference Guide. Saving the edits and updating the schematic When you choose Save from the File menu, two things happen: ■ The Model Editor saves the model definition to the model library. ■ The schematic page editor updates the Implementation property value to Q2N2222-MC for the Q6 part instance. In this example, the default model library is MY.LIB. If MY.LIB does not already exist, the Model Editor creates and saves it in the current working directory. The schematic page editor then automatically configures it as a design model library for use with the current design only. Now you are ready to set up and run the Monte Carlo analysis. Note: If you verify the model library configuration (in the Simulation Settings dialog box, click the Configuration Files tab and view the Library files list), you see entries for NOM.LIB (for global use, as denoted by the icon) and MY.LIB (for design use, as denoted by the icon) in the Library files list. You can change the model reference for this part back to the original Q2N2222 by following the procedure To change model references for part instances on your design on page 240. Using the Create Subcircuit Format Netlist command (Capture only) The Create Subcircuit Format Netlist command is used from Capture. This command creates a subcircuit netlist definition for the displayed level of hierarchy and all lower levels in your design. Note: The Create Subcircuit Format Netlist command does not help you create a hierarchical design. You need to do this yourself before using the Create Subcircuit Format Netlist command. For information on hierarchical designs and how to create them, refer to the OrCAD Capture User Guide. The schematic page editor does the following things for you:
