Logisim is an educational tool designed to simplify the learning of basic logic circuit concepts. Powered by Java, it aims to bring students closer to the design and simulation of digital logic circuits. Logisim is primarily used for designing and schematically representing CPUs and other central processing units. It offers features like a combinational analysis model for circuit conversions, Boolean expressions, and truth tables. Users can also reuse smaller circuits in larger designs. Circuits can be saved, exported as GIF files, or printed, making Logisim a versatile tool for both learning and practical application in digital logic design.

The content of games with a PEGI 3 rating is considered suitable for all age groups. The game should not contain any sounds or pictures that are likely to frighten young children. A very mild form of violence (in a comical context or a childlike setting) is acceptable. No bad language should be heard. Equivalent to E (low end) and EC (which is no longer used). 435 titles were rated PEGI 3 in 2020.

Logisim Features

Logisim is a powerful and intuitive digital logic design tool that allows users to create and simulate complex circuits with ease. With a user-friendly interface and a wide range of components to choose from, Logisim makes it easy to design everything from simple logic gates to intricate processors. Its simulation capabilities allow users to test their designs in real-time, helping to identify and fix any errors before implementation. Whether you're a beginner or an experienced designer, Logisim is the perfect tool for all your digital logic design needs.

Circuit Design

Create complex digital circuits using a simple and intuitive interface. Connect components to simulate electronic systems.

Logic Gates

Implement logic gates such as AND, OR, NOT, XOR, and more to build logic circuits for various applications.

Simulation

Simulate the behavior of digital circuits to test their functionality and troubleshoot any issues that may arise.

Memory Units

Design and implement memory units like registers, RAM, and ROM to store and retrieve data in digital systems.

Input/Output

Add input and output devices to digital circuits to interact with external components and peripherals.

Timing Analysis

Analyze the timing characteristics of digital circuits to ensure proper operation and avoid timing-related issues.

Logisim FAQ

Blue wires in Logisim indicate that the wire's state is unknown. To fix them, ensure all inputs to the circuit are defined. Sometimes it helps to add input pins and manually set their values. Also, check for any unconnected components or incorrect wiring.

To create a subcircuit in Logisim, design your circuit in a new project. Then, right-click the circuit tab and choose 'Add Circuit.' Name your subcircuit. You can now drag this subcircuit from the explorer and use it in your main circuit.

To make a counter in Logisim, you can use a series of flip-flops (like D flip-flops). Connect the output of each flip-flop to the clock input of the next one. Use a clock pin to provide the clock signal. Ensure the flip-flops are configured correctly (likely using a T or D flip-flop configuration).

To make a register in Logisim, use a set of flip-flops (D flip-flops are common choices). Connect them to a common clock to synchronize load/store operations. Enable the 'load' signal to store data and ensure to wire the data input correctly. Reset and set pins can be used for initialization.

In Logisim, a multiplexer can be used to switch between several input signals to a single output line. First, place the multiplexer component, set the number of inputs. Connect the data inputs and the select lines (control inputs). The output will reflect the input chosen by the select lines.

AlexanderHarris Logisim has helped me a ton in my projects! It’s easy to use most of the time, but sometimes it lags a bit with big circuits. Still, it's pretty reliable! I’d definitely recommend it!

AmeliaClark Really nice app for learning circuits! I appreciate the flexibility in designing, though I wish there were more tutorials available for specific projects. Still, I’m having fun exploring!
