Cadence PSPICE SCHEMATIC Manuel d'utilisateur

PSPICE tutorial: a simple DC circuitWe will learn some of the basic maneuvers of using the Cadence schematic capture program and PSPice engine through

The first wire connection.10

All wires in place.11

Every SPICE circuit needs a ground connection. To add a ground, use the menu (Place -> ground) or click on the “ground” item in the vertical toolba

When the the components were placed, the names and values were set to default values. Generally, we need different component values and would like the

The other way to change names and parameters is to double-click on the part symbol directly (or select it with a single click and choose "Propert

(names and parameters), which can be edited in the dialog.Setting up the analysisNow that the circuit schematic is completed, you are ready to tell PS

4. Time Domain (Transient). This calculates the currents and voltages in a circuit at various points in time, allowing you to make a plot of a voltag

Running the analysisFor a simple DC analysis, we now have everything set up.Start the simulation by choosing "Run" from the "PSPICE&quo

We can also see currents and powers. To view those quantities, click the “I” or “W” buttons in the horizontal tool bar to toggle those quantities on

(Note that PSPICE follows the text-book practice of defining generated power as negative. In the example above, the VS1 and IS both have negative valu

Another dialog opens that asks if you would like to create a blank project or start a new one based on an existing project. Since there is no existin

Placing parts, editing parts, and wiring the circuitStart the circuit definition by placing some resistors. Select "Part" from the "Plac

Add the analog and source libraries to your project. (Add them one at a time – select “analog” from the list and then click on the “Open” button. Th

When you are satisfied that you have the right part, double click on the “R” item in the list. You will be returned to the drawing window. The symbol

A resistor symbol will remain attached to the cursor, so that you can place more resistors for the circuit. Place two more horizontally-oriented resi

Use the same procedure to place two DC voltage sources (VDC in the source library) and one current (IDC in the source library) in the drawing window,

Now that all the parts are located in approximately the correct positions, we can use the wire tool to connect the them. Select the "Wire" i
