Logossim: um simulador lógico web de código aberto

Abstract

Digital circuits are the basis of all digital systems that permeate our lives. Knowledge of digital logic is considered fundamental in the fields of Informatics, Engineering, and Computer Science. The use of simulation tools helps students around the world to better understand this topic, putting their knowledge to the test. This work presents the Logossim project: an open-source logic simulator created for the web, easy to use, and easily extensible. This project was built to resemble Logisim, an acclaimed digital simulation software. To achieve this, a simulation engine, a set of digital logic components, and a graphical interface were developed. This project was developed using JavaScript and using React, React Diagrams, and Web Workers as its main technologies. As a result, Logossim is publicly available on the internet and can be used by anyone to study or validate digital logic circuits.
