CHAPTER 1
INTRODUCTION
The digital circuit designed by the use of logisim simulator. Logisim is an educational
tool to support designing and simulating digital logic circuits. And it has the simple toolbar
interface and simulation of circuits. It is easy to learn the concepts of logic circuits. It has the
capacity to build the large circuits from small sub circuit. And it is used to draw the bundles of
wires with a single mouse drag. Logisim is used to design and simulate the whole CPU for
educational issues. It was designed by Carl Burch. Logisim is used by students in college at
many classes. The user can draw the circuit’s logic gates using the toolbox model to drawing
programs. The circuit had generated the values automatically by using major tool. And the user
can change the switches and check how the circuits act in the situations (Al-Busaidi, 2013).
CHAPTER 2:
LOGISIM SIMULATOR:
Logisim means logic simulator. They are used to allow the circuit design and simulation.
GUI (Graphical User Interface) are used to perform the circuit design process. Logisim are
support types of operating system such as Windows, Linux, macOS. The main advantage of
logisim is a free software design (Burch, 2002).
Mostly logisim are used to design the digital circuit, and also done some experimentation.
Traditional drawing programs are mostly similar to the circuit design using GUI. In logisim it
allows the user to edit the circuit. Suppose there was a problem in this circuit we can easily
modify the circuit. This software is mainly used in educational purpose.

2.1 LOGISIM SIMULATOR DESIGN:
2.2 FEATURES OF LOGISIM SIMULATOR:
 Logisim supports many machines but these machines have languages and
operating system like java5 and the windows or macOS.
 Logisim is open-source. So we did not need any resources.
 Toolbars are used for drawing purpose and also color coded wires are used to
debug the circuits.
 Writing tool is used to draw the horizontal and vertical wires.
 The wire components are connected automatically so it can be design the circuit
easily.
