Basic of using ps-pice

1.    To get started:

·         Choose File-New-Project.  When the New Project dialogue box appears make sure that “Analog or Mixed-Signal Circuit Wizard” is selected.

2.    Getting the Parts:

·         Go to icon  to select the part (but make sure you add all the required library first)

·         To rotate-right click or Ctrl+R

3.    Draw wire

·         Go to icon

·         To end the wire push ESC OR right click-end wire

4.    Ground

·         Go to icon  and choose the type according to your circuit

-Any mistakes in placing the part or wire just click on the it and push DEL

-If you want to go back to the previous step from the Edit menu, choose Undo, or click  .

-To get bigger view push I to get smaller view push O

-Common mistakes:

1.    Incomplete circuit: Before running the simulation make sure all the components are connected. To do that simply drag the part anywhere around the screen if the wire is following the part means that it is completely connected.

2.    Do not add space when you write on the value of the part eg:1V

-In the lab session there is only 2 analysis type conducts:

1.     Bias Point (to find V, I and W value without graph)

• By clicking (enable) all this three boxes   will display the voltage, current and power at certain points within the circuit.

2.    DC sweep (to create graph)

Allows you to do various different sweeps of your circuit to see how it responds to various conditions eg:

·         voltage,

·         current,

·         temperature, and

·         parameter and global

You need to specify a start value, an end value, and increment value.

To change the voltage to current diode go to Plot-axis settings-x axis-axis variable select diode current OR from Pspice-edit simulation file-click on current source

-Labeling Node can be done using aliases. Label your input and output nodes will make your node easier to find.  V(Vout) is simpler than finding V(R1:1). Here is how you do it:

·         Go PlaceàNet Alias… In the dialogue box, type name ‘Vout’ 

·         Next, place the mouse pointer on the wire and click.
