Best Free Electronics Circuit Simulation Software

In this article, we will look at free and open-source electronic circuit simulation software. This software allows us to design, analyze, and test a circuit virtually in a browser or on a computer. They simulate the behavior of an electronic device or circuit. We often use them because they are cheaper and quicker. Another use is that it is often more practical to simulate a circuit first than to physically build one. The programs below may provide either analog or digital simulation capabilities or both, have a schematic editor, a waveform viewer, support resistors, capacitors, diodes, etc.

Circuit Simulation Software

In the following, we explore a series of free online and computer software tools for circuit simulation. Some of these may be online tools for circuit simulation.

Online or Web Based Software

Here we are listing a couple of free online circuit simulators for you to try out. The main advantage of these circuit simulators is that they do not need to download them on the computer; rather, they can work directly from the website.

Circuit Sims

It was one of the first open-source web-based circuit simulation programs. It’s an excellent tool for both students and electronic enthusiasts. Its design is based on colors that can indicate, for example, positive or negative voltage and allows us to build simple circuits using a mouse. Regrettably, the developers were unable to make the leap in quality and increase the graphical user interface.

Every Circuit

It is electronic simulation software online with well-made graphics. When we enter the online program, it will ask us to create a free account so that we can save our projects. It has a limited portion of the area to draw where we can draw our circuit. To use it without limitations, it demands an annual fee of $10. We can also download and use it on Android and iTunes. The components have a limited ability to simulate with the minimum parameters. It is very easy to use and has a great system of electronic design. It allows us to embed simulations on our web page.

EasyEDA

EasyEDA is an amazing free online circuit simulator that is very suitable for everyone who loves electronic circuits. It is similar to LTspice IV, but with a somewhat more friendly interface. This simulator is also very powerful, as it can verify analog, digital, and mixed signal circuits with spice subcircuits and models to get results quickly from the cloud-based servers. The software environment allows us to design schematics and check operation with a circuit simulator. When we make sure the circuit function is good, we can create a printed circuit board using EasyEDA. On the website, we can find and use many projects and electronic circuits made by others because they are public and open hardware. It’s free and also allows us to share our work with others.

Computer Software for Circuit Simulation

Computer software offers different ways to manipulate and organize electrical circuits, including the possibility to import files, share, and work with complex electronic schemes. In the following, we have a series of computer software tools to draw and simulate electronic circuits and diagrams.

Qucsis

It is circuit simulation software with a graphical user interface. The software aims to support all kinds of circuit simulation types, e.g., DC, AC, S-parameter, transient, noise, and harmonic balance analysis. This software also supports digital simulations. Qucsis works on almost any operating system, such as Solaris, Apple Macintosh, Microsoft Windows, FreeBSD, NetBSD, etc. The program is released under the GNU General Public License in source code form, so we need to compile it before running it.

LT Spice Simulator

This electronics circuit simulation software is available from a mainstream analog chip company, Linear Technology. It works on Windows and OS X. Although it is biased towards using their parts, it is flexible and can be used with other vendors parts. LTspice has a much faster simulation of switching regulators with enhanced SPICE (compared to normal SPICE simulators). LTspice gives access to over 200 op-amp models, transistor models, MOSFET models, etc. A high disadvantage of LTspice is its proprietary code base, which is licensed by Linear Technology. Had they made it open source, LTspice could have easily integrated collaborative development.

Ngspice

This electronics circuit simulation software is a mixed-level, mixed-signal circuit simulation engine based on three open-source software packages: Spice3f5, Cider1b1, and Xspice. Ngspice is part of the gEDA project, a full GPL’d suite of Electronic Design Automation tools. It works on Linux and FreeBSD systems.

MultiSim National Instruments

The Multisim electronics circuit simulation software is based on Berkeley SPICE and comes with both free and paid additions. MultiSim, the circuit maker software, enables us to capture circuits, create layouts, analyze circuits, and simulate. Highlight features include exploring breadboards in 3D before lab assignment submission, creating printed circuit boards (PCBs), etc. Breadboard simulation is possible with the Multisim circuit simulator. It’s available on Microsoft Windows.

Proteus

Proteus is a mixed-mode, spice-based electronics circuit simulation tool from Lab Center. They have two versions: basic and advanced. The basic version is free and supports interactive simulation only. While the advanced version supports a range of useful functions and features like graph-based analysis, which includes frequency, noise, distortion, Fourier parameters, etc. The software runs on the Windows operating system.

CircuitLogix

This is student-version electronics simulation software from CircuitLogix. It enables us to perform analog, digital, and mixed-mode circuit analysis and simulation. This SPICE simulation software provides 4000 devices in its student version, which is 1/3 of the pro version. This circuit-building software gives access to switches, linear and digital ICs, FETs, transistors, relays, displays, signal generators, SCRs, opto-isolators, photodiodes, semiconductors, motors, etc. It works on Windows systems.

XSPICE

This was developed as an extension to Spice 3 by the Georgia Institute of Technology. It has a code modeling feature that enables users to add new models. Its code model library includes functional blocks like multipliers, summers, integrators, magnetic models, limiters, S-domain transfer functions, digital gates, etc. The program provides source code, and its release is in the public domain.

  5. I am currently trying to simulate a huge circuit which involves parallel working of 2 PIC and an ATmega328p U. I can’t simulate it on Proteus because of an error ” Simulation can’t be done because of excessive CPU load ” , so can someone recommend me any other software simulator which can handle a big circuit ?

    1) I need help. I will not take the time to explain my actual problem. Nor will i put any effort whatsoever into solving my own problem. You should help me.
    KTHXBYE

    2) Ah I see you have taken the time to look at many different tools to do circuit simulations! I also see that you have written a quite detailed description of each, and even compared them with each other. That must have taken a long time! Now, please further simplify this for my specific needs. I will not tell you these needs. But you should do it.
    Oh if you do I will be verrrrrrrrry thankful winky winky winky you know what im sayin right heh hehe heh I mean like REALLY thankful…. .. . .

    • Do you know something????? When you have spent a LOT of time in learning a discipline and someone tells you, “I know some programs that may help you with your studies. BUT, you have to stop what you are doing and spend your precious time learning a whole new discipline to be able to use that help.”

      Who has time for that??!!!
