Use of PSPICE for Resistive Circuits
DC Resistive Circuit
 | Start by getting parts from PSPice schematic libraries. |
Hit <Crtl G> and enter the part name:
R for a resistor,
C for a capacitor,
VSRC for a dc voltage source,
Agnd for analog ground
Viewpoint for getting voltages at any node in the circuit
Probe for getting currents in branches
An example on how to select a resistor is shown below:
| Place the components in proper locations according to the circuit diagram.
You can use the following to rotate and flip parts: |
<Ctrl R> to rotate
<Ctrl F> to flip a part
(Note: these commands are not case sensitive)
| In order to provide connections between parts, use: |
<Ctrl w> to get a wire.
To connect a wire between two elements, hit <Ctrl w> and start by clicking the
left button mouse (LBM) on the starting point, moving the mouse to the ending point, and
clicking again on the LBM. Notice that the line you drew is red, which means that it is
still under editing (you can delete it or move it, etc). Move the mouse away from this
line and click once on the right button mouse (RBM) to exit the editing mode. Notice that
the line color turns green.
| In order to set a value for a part, select the part by clicking on it once with the
LBM, then double click with the LBM to bring the attribute dialog box and set
the value by highlighting the <value> from the menu and typing the value in the
prescribed box. For this example, the voltage source was set to 16V. The
following shows the attribute setup: |
| The final circuit will look like:
|
| In order to simulate, hit <F11>. The simulation results will like:
 |
Notice that the voltage across the nodes are written by the viewpoint parts
and the currents in branches are written by the iprobe parts.
