23 Best Free Circuit Simulation Software For Windows

Here is the list of Best Free Circuit Simulation Software For Windows. These freeware let you design as well as simulate circuits on your PC. Using these software, you can actually checkout how a circuit will behave, and also know additional information including its waveform. If you are specifically looking for Circuit Design Software, look here.

There are various types of circuit simulation software that have been mentioned in the following list. Some are electric circuit simulator, some are electronic circuit simulator, some spice circuit simulator, and some power electronic circuit simulator. The simple circuit simulator listed here let you carry out only one type of circuit design and simulation, while the advanced ones can carry out circuit simulation for multiple types of circuits. For example idealCircuits and QUCS; these software let you design and simulate both electrical and electronic circuits on your PC.

You just have to add components from the component list that these circuit simulator freeware provide and run simulation.

Go through the list and you will find out about the mentioned software in detail. I have described these software in such a way that you will find it easy to select what you actually need.

My Favorite Circuit Simulator Software:

In my opinion, almost all of the mentioned software are good choices, and what I will use will totally depend on my need. If I had to make a choice, I will go with idealCircuit. It has almost all the components required to design electrical and electronic circuits. If I had to design and simulate just electric circuits, I would go with Tina-Ti.

You can also checkout the list of best free Oscilloscope Software and Signal Generator Software.

Tina-TI

Tina-TI is a free circuit simulation software that can be used to design and simulate circuits. You can also check a circuit for errors before simulating it. Carry out DC analysis, AC analysis, Transient analysis, Fourier analysis, Noise analysis, etc. after designing a circuit. Tina-TI is an Electrical circuit simulator and lets you simulate Spice circuits as well.

Here, you are going to find almost all components required to design a circuit. Also, you can change component values according to your choice. For example, if you take a voltage source, you can customize its voltage level, voltage waveform, etc. You will not only find basic electrical and electronic components, but advanced ones as well. Basic components available here are Voltage source, Battery, Voltmeter, Ammeter, Resistor, Capacitor, Inductor, Transformer, Switch, Jumper, etc. Advanced devices include Relays, Meters, Data Generators, Semiconductors (Op-Amp, Diodes, and Transistors), and Spice Macros (Amps, Comparator, SMPS, Converters,Buffer, etc.).

Talking about circuit design and circuit simulation, this software lets you do it with ease. The component list is handy and placed on top of the circuit board. This makes it easy for users to design a circuit. Also, to change component values, a double click on it is all it takes.

Run an Electric Rules Check from the Analysis menu to know if there’s any error in the designed circuit. So, if there’s something wrong, you’ll get to know beforehand. For the circuit I designed (above picture), I was suggested to add Ground connection to voltmeter and voltage source.

To simulate a circuit, go to the Analysis menu and carry out the type of simulation and analysis you want to. I have already mentioned the analysis options available in the first paragraph.

If you need to further analyze a circuit and its output, then you can make use of Multimeter, Oscilloscope, XY recorder, and Signal Analyzer.

A designed circuit can be saved on your PC as schematics file or you can export it as an image, XML, or Netlist.

It is one of the best circuit simulation software out there and highly recommended.

idealCircuit

idealCircuit is an amazing circuit simulation software. It lets you carryout electrical circuit simulation as well as electronic circuit simulation. Most of the software listed here provide either of the simulation options, so this can be your pick if you need both electronic and electric circuit simulator software. Another impressive feature about this software is that, there are 3 tabs available here for circuit design, simulate and view resultant waveform, and to view AC parameters of the simulated circuit.

You get a good list of components to design circuit. You can also load a circuit in .ic format to simulate it. Let us checkout the list of components:
