History of Multisim.?
Multisim was originally called Electronics Workbench
and created by a company called Interactive Image Technology. At the
time it was mainly used as an educational tool to teach electronic
technician and electronic engineering programs in colleges and
universities. National Instruments has maintained this educational
legacy, with a specific version of Multisim with features developed for
teaching electronics.
In 1999, Multisim was integrated with Ultiboard after the original
company merged with Ultimate Technology , a PCB layout software
company.
In 2005, Interactive Image Technologies was acquired by National
Instruments Electronic Workbench group and Multisim was renamed
to NI Multisim.
What is Electronic Workbench/ Multisim.?
Electronics Workbench/Multisim are simulation programs
for educators and engineers that can model the behavior of
analog / digital circuits and provide a means of analyzing
them in a safe and efficient manner.
Benefits of Multisim:
Provides real-life experience not readily available due to
lack of resources.
2. Costs less than the physical equipment that’s why it
motivates the learner.
3. Experiment in a safe environment.
1.
Limitation of Multisim
Simulation can not really substitute for real – life practice
at handling components (e.g. soldering)
2. Cost (personal copy)
3. Lack of technical support
1.
User Friendly:
Quick access to the most commonly used tools.
2. Components are well organized and easy to find.
3. Simple procedures in developing circuits.

 To place components on the window, you can:
 Click on the component toolbar, then browse for
the part.
 Click Place on the menu bar,
select components, then
browse for the part
First Place Power Source & Ground.
Now Select DC Power Source from there respective
families (source) and click OK...
Next, we need to add a Ground. The Select Component
window automatically opens after the first component is
placed, so all you need to do is click Ground then click OK.
If your component window did not automatically open,
click the Place Source button to reopen it.
Select Ground & click OK….
Next, we will place Transistor from
Transistor Menu.
Under Group, click the
drop-down arrow and
click Transistors.
Choose the Required Transistor (nPn & PnP)
From Transistor Families.
Select BJT_NPN then Search BC547 & Click OK place it on
work place… Place 3 times the same transistors on work
window.
After Placement of these components the work
window look like this. Now we can repeat the part
placement to place a switches and resistors. See if you
can find the switches in the Basic Group.
Place a switch. Choose the switch labeled SPST for single
pole, double throw. Then place another switch like this.
Place a resistor. Choose the 1K value resistor from the
resistors sheet & click OK... Another resistor of value 4.7K
also place by same method.
We have placed all of the components that
we need for now. For close Components
Box Click Close Button.
Parts can be moved. Make sure that the
component has a Bar box around it. Arrange the
components to match the above configuration.
According to your circuit designing, you can rotate, Flip
vertical or horizontal and change setting (of some
components like switches) etc. This is done by right click on
selected component then menu will appear.
If you want to change the value of the components like
(Sources, resistor, capacitor etc.). Double-click on that
component a dialog box will appear from where you can
change your values.
Example: you want to change
the resistance value double
click on it.
Enter your new
value here
Wiring the Components

To begin wiring, how over the cursor over a
part terminal (end pin). Notice that the
cursor changes shape to indicate that you
are starting a wire.
Cursor shape changes, showing that a wire is
beginning on the ground symbol.
Click once. Now you can start the wire. To end the
wire, click on another terminal.
Circuit window after connection
between Vcc & Resistor R1.
Continue Wiring
• Click on the top of the source. Move the cursor to
the right terminal of resistor R2 and click again.
This should draw a wire connecting the parts.
• Continue wiring the circuit until you have a
complete circuit.
• After completing the wiring you must check it the
connections is correct, if any mistake is found you
correct it and simulate the circuit.

Assignment… (submit soft and hard copy)
Design a CMOS NOR gate circuit and simulate it.
Also proves all the NOR gate results.
Analyzing of NAND Gate by Digital
