Hello friends,

I hope you all got benefited with our previous article on Electronic circuit drawing softwares .

Today we are bringing you a great collection of circuit simulators – which are at the same time can be used for circuit drawing, circuit design and analysis as well. The list is well structured as free circuit simulation softwares, open source circuit analysis and simulation software, simple and easy to use simulators, linux based simulator, windows based simulator etc. Finally after researching through all the list we have compiled a collection best circuit simulation softwares as well. So lets start our journey right below.


Free and Open source circuit simulator software list:-

NgSpice – one of the popular and widely used free, open source circuit simulator from Sourceforge. NgSpice is developed by a collective effort from its users and its code is based on 3 open source software packages:- known as:- Spice3f5 , Cider and Xspice. Ngspice is a part of gEDA project which is growing every day with suggestions from its users, development from its contributors, fixing bugs and approaching perfection. As its a collaborative project you can suggest improvement of the circuit simulator and be a part of the development team.

GnuCap – is another open source project, developed as a general purpose circuit simulator. Known widely as GNU Circuit analysis package, this linux based circuit simulator performs various circuit analysis functions as dc and transient analysis, ac analysis etc. Developers have incorporated spice compatible model for MOSFET, BJT and Diode.

EasyEDA – EasyEDA is another free software that doesn’t require downloading. You can just signup and use the software, you can even try it without a signup but to download/save what you made you have to have an account which is ofcourse free.

CircuitLogix – this student version software from CircuitLogix enables you to perform analog, digital and mixed mode circuit analysis and simulation.  This SPICE simulation software provides 4000 devices on its student version which is 1/3 of the pro version. This circuit building software give access to switches, linear IC and digital IC, FET, Transistors, relays, displays, signal generators, SCR’s, opto isolators, photo diodes, semiconductors, motors etc.

LTSpice – is a widely popular SPICE simulator from Linear. LTspice is a free circuit simulation tool from Linear Technology corporation. This simulation software is considered as one of the best freeware available. Highlight of LTspice is much fast 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 gone places with collaborative development.

Note: LTSpice is considered as the BEST circuit simulation software available by users.

MultiSim – is a student version circuit simulation software from National instruments. As you know, student versions always comes with limited access. Still this is a great simulation tool for beginners in electronics. MultiSim, the circuit maker software enables you to capture circuits, create layouts, analyse circuits and simulation.

It offers both Pspice and Hspice compatible simulation of circuits.

Circuit Simulator 1.5j – is a freeware circuit simulation tool. I have not used this tool or even attempted a try. I add this as a suggestion from a user in our forum. I think this is just basic tool with very basic functions, created for starter purpose. Use at your own risk.

MacSpice – is a free circuit simulation software for Apple Macintosh users. This circuit simulation which is compatible with PowerPC and Intel architecture Apple Macintosh (MAC pc) computers is derived from Berkeley Spice 3f5 . This breadboard simulator can perform simulation ranging from a single resistor to an integrated circuit with thousands of devices and components packed together.

SimScale – SimScale is a cloud-based simulation software which you can do everything online. They have a free community plan which you can signup for but all the circuits you make will be publically available.

Micro-Cap 10 – is another demo version circuit analyzer and simulator from Spectrum Soft. As they claim its a mixed mode digital/analog circuit simulator with an intuitive user interface, fast simulation and great performance. I haven’t tried this yet, so if you are interested try your own.

PECS – is a free power electronics circuit simulator created by Richard Tymerski. You can download the various manuals and tutorials from the website before start using the simulation tool.

Proteus – Prospice is a mixed mode, Spice based simulation tool from LabCenter. They have two versions, basic and advanced. Basic version is free which supports interactive simulation only while advanced supports a range of useful functions and features like graph-based analysis which includes frequency, noise, distortion, fourier parameters etc.

QUCS – Quite Universal Circuit Simulator is a free simulation software developed on GNU/Linux environment. Well, this software really works on other operating systems such as Solaris, Apple Macintosh, Microsoft windows, FreeBSD, NetBSD etc. User can simulate large signal, small signal and noise behavior of the circuit using this simple circuit simulator.

Solve Elec – is an electrical circuit simulator (free version) which is developed for Macintosh OS and Windows. It enables users to draw and analyse circuits (both electrical and electronic) functioning in direct current or alternating current, get formulas, verify equations, get equivalent circuits etc.

Okay! So far we have listed 16 free version circuit simulators, some of which are open source, some are licensed but free, some are demo/ student versions etc. And we have atleast one simulator for each and every operating system out there in the market. If you know some other free simulation software/tool, that’s so great, please share it as comments.

Now let’s have a look at some enterprise circuit modelling software in the market.

Best Licensed/Paid Circuit simulation software:

If you are an Electrical and Electronic engineer then there are some software that you must have in your arsenal such as PCB Design Software, Circuit Design and Simulation Software, etc. Therefore, in this article, we present you with some of the best free Circuit Simulation Software for Windows 10.

Best Circuit Simulation software

With the help of these Circuit Simulation Software, you can design and analyze circuits without actually building one:

  1. LTSpice
  2. NgSpice
  3. CircuitLab
  4. CircuitLogix
  5. EasyEDA

Let us talk about them in detail.

1] LTSpice

Best Free Circuit Simulation Software for Windows 10

LTSpice is one of the most famous Circuit Simulation Software among Electrical and Electronic Students. Developed by Linear Technology, it has an array of different devices, so, you won’t be missing out on something, as it has MOSFET, OPAMPS, diodes, Triac, Diac, and some other basic electronic devices such as a capacitor, resistor, and inductor.

One of its biggest selling points is its speed. LTSPice is probably the fastest simulator on our list. So, if you have a need for speed then you know which application will fulfill your appetite. LTSpice also has a Waveform detector, so, you can have a more clear perspective of your output. LTSpice has tons of bells and whistles that you will only if you download the software from here.

2] NgSpice

Another free open-source Circuit Simulation Software on our list is NgSpice. It is one of the most popular tools alongside LTSpice.

One of the reasons why some people may choose NgSpice over LTSpice is its community support. Its source was build by accumulating the concept of three open-source packages, XSpice, Cider, and Spice3f5. Its developers are constantly working to make this software better by releasing new builds and updates with bug fixes.

You will get all the electronic components, such as resistors, diodes, capacitors, and other such devices. So, if you are looking for a free Circuit Simulator then get NgSpice from here.

3] CircuitLogix- Student Version

If you are a student then you can use this student version circuit simulation tool from CircuitLogix. However, you should not download this software expecting professional-level tools as the commercial version of the software has.

Student Version is just another name of the lite version. You won’t get everything, but, for some people, the commercial version is a bit of an overkill. You will get almost 4000 devices in the Student version, which is not even 33% of what you will get if you go for the pro version, but for most people, it is more than enough.

So, if you are an electronic student then Circuit Logix Student Version can a perfect Circuit Simulator for you. If you decide to go for this software, download it from their official website.

4] CircuitLab

If you don’t want to download an application then CircuitLab is what you need. It is an online circuit simulator and schematics tool. It doesn’t have all the bells and whistles unlike the previous two applications on our list, LTSpice, and NgSpice, but is an excellent alternative if you just want to make a basic circuit and simulate it.

You are getting all the necessary devices such as all the passive elements (resistors, capacitors, inductors), MOSFET, BJTs, JFETs, Relays, and other such components. It is a nice tool especially if you want to learn circuits. You can access CircuitLab from their official website.

5] EasyEDA

Last but least, we have another online Circuit Simulation tool, EasyEDA. It is a simple tool that can double as a PCB Designer, but here we are talking about its Circuit Design and Simulation capability and that’s no joke.

EasyEDA has tons of devices and you won’t feel like you are missing out on anything in particular. However, these online tools are not as powerful as freeware. But, if you just want to design and simulate circuits then it is a nice option and can be accessed from their official website.

Hopefully, this has helped in finding the best Circuit Simulator for Windows 10.
