Some of these are generated by the design entry tool, others come from libraries (which can also be generated by other programs like the PSpice Stimulus Editor and the PSpice Model Editor), and still others are user-defined. Note: You can choose File –Open File Location from PSpice to open the location of PSpice files.

These files are the netlist file and the circuit file that PSpice reads before doing anything else. Design Entry HDL files: When you begin the simulation process, Design Entry HDL generates a netlist file describing the parts and connections in your design. In the earlier releases these files were in the cfg_analog view. But in the new format all the PSpice related files are located in the psp_sim_1 view.
