How to Import PSpice models into Proteus

Select the Voltage probe and place it on the transistor collector

click on Graph Mode button and choose ANALOGUE to perform later a transient analisys, let’s size the graph window on the layout

drag the voltage prob inside the window

now we have to link the symbol of NPN device with the SPICE script: right click on the symbol and select “Edit Properties”, the “Edit Component” window opens,  write “ANALOGUE,NPN” in “Simulator Primitive Type” field and “SPICEMODEL=QBF199” inside “Other Properties” text editor

Click on “Ok” to close the window, the NPN symbol is now linked to the script

Right click on the graph window, select “Edit Properties” and set a stop time to 200n (nanoseconds)

press space to perform a transient analysis
