2 Introduction to Proteus
Professor: Dr. A.H. Rezaee Prepared by: Ehsan Esmaili

3 In this presentation I have used proteus 7 professional

4 Preface Proteus is one of the most famous simulators. It can be used to simulate almost every circuit on electrical fields. It is easy to use because of the GUI interface that is very similar to the real Prototype board. Moreover, it can be used to design Print Circuit Board (PCB).

5 A Guide To ISIS Overview Window Editing Window Object Selector

6 Tools and Buttons Selection Mode Component Mode Pick a Device Ground and terminals Signal generators(sources) Instruments(Scope, meters)

7 Tools and Buttons Device rotation Stop the simulation Device flip Run a simulation

8 (1) Click on P to pick a device.
How to pick a device? (1) Click on P to pick a device. (2) Type Resistor to search for (3) Double click on Resistor to select (4) Notice the Resistor in the Object Selector

9 How to draw a Circuit? We draw a following simple circuit as our first circuit: GO

10 An Analog circuit: The following is one of the circuits that I’ve designed for Electronic laboratory: GO

11 It’s time to design a digital circuit!
Getting acquitted with logic gates: AND Exclusive OR p q p . q 1 p q p ⊕ q 1 GO

12 BUT what we see in laboratory is different!
We don’t have in real world!!

13 So our circuit in pervious slide in laboratory will be:

14 Another way to analyze digital circuits:
Analyze by digital signal GO

15 Full Adder (3-bit Adder) circuit :

16 BCD to Seven-segment display:

17 4-bit Magnitude Comparator:

18 BCD adder and display result on a 7segment:

19 3×8 Decoder: LED Matrix: GO

20 Simulating big circuits in Proteus
It’s possible to simulate big circuits in Proteus with common methods that we learnt. But the common methods are not suitable for big circuits. we should use more advanced methods that I will explain to you. The advanced methods make the circuit easier to understand and reduce possible errors.

21 Subcircuit and Terminals
We should divide our big circuit to smaller parts called subcircuit. It reduces possible errors and makes team working possible. we should use terminals to make the circuits easier to understand by reducing the wiring.

22 How to make a subcircuit? and How to draw the circuit by terminals?
