Introduction to Proteus

Professor: Dr. A.H. Rezaee

Prepared by: Ehsan Esmaili

In this presentation I have used proteus 7

professional

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).

How to draw a Circuit?

We draw a following simple circuit as our first circuit:

GO

An Analog circuit:

The following is one of the circuits that I’ve designed for Electronic laboratory:

GO

It’s time to design a digital circuit!

GO

Getting acquitted with logic gates:

p q p ⊕ q

1 1 0

1 0 1

0 1 1

0 0 0

p q p . q1 1 1

1 0 0

0 1 0

0 0 0

AND

Exclusive OR

BUT what we see in laboratory is different!

We don’t have in real world!!

So our circuit in pervious slide in laboratorywill be:

GO

Another way to analyze digital circuits:

GO

Analyze by digital signal

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.

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.

How to make a subcircuit?and

How to draw the circuit by terminals?
