Free Electrical Circuits Simulator Download

EKTS (Electrical Control Techniques Simulator) is an electromechanical system design simulator. It allows you to create a wide range of electromechanical systems with the help of relays, time relays, buttons, motors, switches, and some basic mechanical components.

EKTS allows you to create unique motor circuits with a variety of motor types and amounts. Because the primary goal of this simulator is to teach the fundamentals of electromechanical systems, it includes an error pointing function that displays the specific location of the problem as well as the reason for the error.

Another valuable feature is a list of all circuit elements that can be used to calculate price and define parts that will be used.

Because EKTS does not calculate current flow and power distribution through circuit elements, it cannot ensure that the same result will be obtained in the actual world. Before using created circuits in a real environment, we strongly advise getting supervisor approval.


  • Create and test Circuits with electromechanical components
  • Examine the fundamentals of operation and the current flow procedure in a circuit.
  • Create bespoke motor circuits by combining different motor types.
  • To prepare study materials, print out the circuit or save it as a picture.
  • GIF, BMP, JPEG, and PNG image formats are supported.
  • Before putting circuits on the plant, make sure they work.
  • To specify their configurable state, make a list of the elements that are used.

Free and Open source circuit simulator software list:-

Ng Spice –

One of Source forge’s most popular and commonly used free, open-source circuit simulators. NgSpice was created by a community of users, and its code is built on three open-source software packages: Spice3f5, Cider, and Xspice. Ngspice is part of the EDA project, which is developing every day thanks to user recommendations, contributor development, bug fixes, and the pursuit of excellence. You can offer improvements to the circuit simulator and be a part of the development team because it is a collaborative effort.

Gnu Cap –

is a general-purpose circuit simulator that was built as an open-source project. This Linux – based circuit simulator, also known as GNU Circuit Analysis Package, provides circuit analysis functions such as dc and transient analysis, ac analysis, and so on. Spice compatible models for MOSFETs, BJTs, and diodes have been included by the developers.

Easy EDA –

Easy EDA is yet another free program that does not require installation. You can just join up and use the software; you can even try it out without registering, but you’ll need an account to download/save what you’ve created, which is, of course, free.

Circuit Logix –

Circuit Logix’s student version software allows you to analyze and simulate analog, digital, and mixed-mode circuits. The student version of this SPICE simulation software has 4000 devices, which is a third of the pro version. Switches, linear and digital ICs, FETs, Transistors, relays, displays, signal generators, SCRs, isolators, photodiodes, semiconductors, motors, and other components can all be found in this circuit construction program.

LT Spice – 

Linear’s SPICE simulator is very popular. Linear Technology Corporation’s LT spice is a free circuit simulation tool. This simulation program is regarded as one of the greatest freeware programs available.

The quick simulation of switching regulators using enhanced SPICE is a highlight of LT spice (compared to normal SPICE simulators) Over 200 op amp models, transistor models, MOSFET models, and other models are available in LT spice. The proprietary code base of LT spice, which is licensed by Linear Technology, is a significant disadvantage. LT spice could have gone a long way with collaborative development if it had been made open source.

Multi Sim –

is a student edition of National Instruments’ circuit simulation software. Student versions, as you may know, always come with restricted access. Even so, for beginners in electronics, this is an excellent simulation tool.

The circuit creator software Multi Sim allows you to capture circuits, design layouts, analyze circuits, and simulate circuits. Explore the breadboard in 3D before submitting a lab assignment, create printed circuit boards (PCBs), and more. Multisim circuit simulator allows for breadboard simulation.

Top Spice –

This is a Penzar circuit simulator demo version. This electronic simulation tool is designed specifically for Windows and is compatible with Windows XP/Vista/7. Top Spice is a behavioral simulation software that uses mixed mode mixed signal digital and analog signals. It supports both P spice and H spice for circuit simulation.

Circuit Simulator 1.5j –

is a circuit simulation program that is available for free. I haven’t used this tool or even tried to use it. This is a suggestion from a user on our forum, therefore I’m including it. I believe this is a rudimentary tool with very basic functions, designed for beginners. You should use it at your own risk.

Mac Spice –

For Apple Macintosh users, is a free circuit simulation software. Berkeley Spice 3f5 is the source of this circuit simulation, which is compatible with PowerPC and Intel architecture Apple Macintosh (MAC pc) computers. This breadboard simulator can simulate everything from a single resistor to a complex integrated circuit containing hundreds of devices and components.

Sim Scale 

Sim scale is a cloud-based simulation software that allows you to complete all of your tasks online. You can join up for a free community plan, but all of the circuits you create will be publicly viewable.

Micro-Cap 10 

Spectrum Soft has released yet another demo version circuit analyzer and simulator. It’s a mixed-mode digital/analog circuit simulator with an intuitive user interface, quick simulation, and high performance, according to the developers. I haven’t tried it yet, but if you’re curious, give it a shot.


Richard Tymerski designed a free power electronics circuit simulator. Before you begin using the simulation tool, you can download the numerous manuals and lessons from the website.


Lab Center’s Prosise is a mixed-mode, Spice-based simulation tool. Basic and advanced versions are available. The basic version is free and only offers interactive simulation, whereas the advanced version includes a variety of helpful functions and features such as graph-based analysis with frequency, noise, distortion, and Fourier parameters, among others.
