give your project a name. Second, make sure that or is selected (click on the “Analog Mixed A/D” circle to the left if the this option as shown in the figure), this allows PSPICE dot doesn’t indicate simulations. Finally, make sure that the location at the bottom is either the shared drive or c:\temp. Change the location with the browse button, or by typing the name in the location box if necessary. In the PSpice Project dialog box, a this is your first “Create select “Create blank project”, since effort. Creating the Circuit We are now ready to start drawing the circuit in the schematic that appears (see “drawing board” next figure). The first thing we need to do is place parts. There are several ways to get the parts we use the drop-down and then The dialog box that need. Let’s “Place” “Part…” options. “Place Part” appears is shown. It is a rather important box, so it in a little detail. All of the parts, we’ll discuss resistors, voltages sources, ICs, etc., have models which detail the properties of these components, and the models are stored in libraries. The same basic part (for example, a digital clock) may have different models in different libraries, and often, these models function the same, so it is don’t always important to know the specific model you are using. Next you need to add the appropriate libraries for the project. In the parts pane shown above, under Libraries select the middle icon which looks like a box with a yellow asterisk. You may need to navigate to the pspice folder in the file selection pop up. Open the 7400 and Source libraries.
