Open a new panel for the DC waveform by clicking on Panels/Add. Return to the
Results Browser or reopen by clicking Tools/Results Browser. Click on DC: Simple
RTL Inverter and repeat part f) to view the DC waveforms.
A model for the MOSFET must first be obtained. Replace npn.mod with scmos.mod in
the .include line of the your netlist and save as MOSinv.sp.
Edit MOSinv.sp by replacing the BJT with a MOSFET in your netlist.
