1 Introduction to PSpice What is PSpice? SPICE is an analog (originally) circuit simulator that was developed at the University of California at Berkeley. What does SPICE stand for? Simulation Program with Integrated Circuit Emphasis What is PSpice? Pspice is a commercial derivative of the SPICE2 circuit simulator that were developed at the University of California at Berkley. PSPICE Student Demo software is available at: http://www.engr.uky.edu/~cathey/pspice0 61301.html I. Generate new project Go File New Project Click OK to proceed.

2 Then Choose blank project You’re ready to start !!!! II. Drawing circuit with PSpice A. Getting the Parts: This can be done by o Clicking on the ‘place parts' button Then, you will have the following window. Here you can choose all the parts that you need to. Some common parts are: o r - resistor o C - capacitor o L - inductor o d - diode

3 o Ground can be placed by clicking GND icon. This is Very Important step !! o VAC and VDC B. Placing the Parts: Simply, drag the part where you want to position. To rotate parts so that they will fit in you circuit nicely, click on the part and press " Ctrl+R " (or Edit "Rotate"). To flip them, press " Ctrl+F" (or Edit "Flip"). If you have any parts left over, just select them and press "Delete". C. Connecting the Circuit: Now that your parts are arranged well, you'll have to attach them with wires. Just click button. Then just click on the parts that you want to connect. To delete the connection, just use ‘delete’ key. To stop the ‘wire’, press ‘Esc’ key. D. Changing the Name of the Part: R1 1k For example , if you placed parts as the left figure, you can change name and value of it by clicking the ‘R1’ or ‘1k’. Then, the above window will pop up, just change the name or value as you want. E. Making Sure You Have a GND: invoke this by clicking

4 This is very important. You cannot do any simulation on the circuit if you don't have a ground. If you aren't sure where to put it, place it near the negative side of your voltage source. Choose ‘0’ for ground. F. Voltage and Current Bubbles: These are important if you want to measure the voltage at a point or the current going through that point. To add voltage or current bubbles, go to the right side of the top tool bar and select "Voltage/Level Marker" (Ctrl+M) or "Current Marker" . To get either of these, go to "Markers" and either "Voltage/Level Marker" or "Current Marker". Also, you can measure voltage difference between nodes.

5 III. Simulation and Analyze Plot A. Before you do Simulation You have to have your circuit properly drawn and saved. There must not be any floating parts on your page (i.e. unattached devices).
