Logisim is an educational and accessible application aimed at the simulation and learning of digital circuits. With it, students and enthusiasts can create and test logical circuits practically, using an intuitive graphical interface that does not require advanced programming knowledge. It allows building everything from simple circuits, like logic gates (AND, OR, NOT), to more complex systems, like registers and basic processors, all with draggable components and visual connections. It includes analysis tools, such as truth tables and real-time simulation, as well as support for subcircuits to organize larger projects. It is an excellent choice for those who want to explore digital electronics easily and visualize the operation of each element in action.
