Best Free Circuit Simulation Software of 2025

Over 1 million real-time updated parts have been created. This allows you to focus on the design and you can also create or import your common libraries. EasyEDA, China's largest distributor of electronic components, supports direct links to more that 200,000 in-stock components at LCSC. Designers have access to stock, prices, and orders at any stage of design. It offers the same features as the online version but has more design areas. We have made many improvements to the product, so we recommend it. It is easy to use. You can use it faster if you have previously used other PCB tools. You can design faster, lighter, and less resource-hungry. Register and log in to use the service, there is no activation required. Local backup automatically with document retrieval at any time. You will also have backups on the cloud server. This doubles your data security.

The graphical interface of the schematic capture tool allows you to explore schematics, produce simulation results and further explore them through the waveform viewer. The speed at which you can grasp the circuit, its correctness and its limitations is crucial to circuit design. LTspice is faster than many other simulation tools, and allows you to iterate designs in a short time. The keyboard shortcuts in LTspice are a quick and easy way to access commands that you would normally only be able to access by clicking on the menu or toolbar. Our vast collection of technical resources covers a wide range LTspice-related topics. Learn how to add third-party model, work with symbols and more.

Easy-wire mode allows you to connect elements with less clicks, and therefore less frustration. The unit-aware evaluation of expressions allows you to plot arbitrary signals, such as differential or power dissipation. You can design and analyze circuits faster with in-browser simulation. This allows you to test your circuit before you ever pick up a soldering tool. Advanced simulation capabilities include frequency domain (small signal simulation), stepping circuit parameters across a range, arbitrary Laplace function blocks, etc. With configurable plotting window, vertical and horizontal marker, and calculations for signals, you can work with multiple signals with ease. With just a few mouse clicks, you can create generic rectangular symbols to represent IC or system level wiring diagrams.

There are many circuit simulators on the market. Just look at their ads: industry standard, high performance, fast, and extremely fast. SPICE), easy-to-use, highly intuitive. Try it out yourself to see if the tool is worth your time. Many NL5 users have already done this. I hope they'll share their inspiring stories soon. What can you expect from NL5? It is neither a replacement for SPICE nor a new SPICE. NL5 is superior for some tasks, good for others, and not suitable for some.

Our online circuit simulation bridges the gap between theory, and practice through an intuitive interface. It allows you design, simulate and share electronic circuits, while observing the interaction of components in real time. Directly manipulating the behavior of circuits makes learning more engaging. DCACLab is a powerful tool for educators. It enhances their lessons with interactive diagrams, live demonstrations, and video. Students can experiment and learn in a safe environment, which will lead to a better understanding of electronics. DCACLab turns frustration into hands-on understanding and learning. Discover the power of an interactive multimeter. It provides a realistic and enriching learning experience with its functions to measure ohms, voltages, and resistances. With ease and understanding, dive into the world of electronic.

One animated circuit is equivalent to a thousand equations or diagrams. The schematic is accompanied by animations of voltages and currents. This gives a great insight into the operation of the circuit. The real-time simulation engine was custom-built to be fast and interactive. Simulate everything from simple logic gates and resistors to complex transistor-level designs and mixed-signal circuits with just one click. You can adjust potentiometers and LED current-limiting resistors while the simulation is running. Your changes will be reflected in real-time. The mini-waveforms that appear on top of the schematic wires are different for digital and analogue signals. Digital wires are color coded, while constant analog voltages are shown in numbers. In the XY mode, any pair of time domain signals can be plotted. The grid ticks and oscilloscope scale are automatically updated to convenient values when the data changes.
