To fix a value onto components and nodes, the user simply adds a label. The ac sources seem to accept any input frequency parameter though there doesn’t seem to be any allowance in the simulations for RF radiation effects. It will also do frequency domain simulations and lets users define arbitrary Laplace transfer function blocks.

And there don’t seem to be much in the way of pre-built circuits in the library.ĬircuitLab-This is a browser-based simulator that includes a pretty big library of circuit elements and pre-built circuits and takes differing units into consideration when evaluating expressions. But we couldn’t figure out whether it was possible to change the frequency of the ac sources or the parameters of the pulse generator. Sources include dc or ac voltage and current sources and a pulse generator. Users build the circuit online using basic passive components, op amps, NPN, PNP, and NMOS transistors. Click image to enlarge.ĬircuitsCloud- This is another package for students. So you would be out of luck if you wanted to simulate a circuit containing transistors-there aren’t even current sources available to create Ebers-Moll transistor models. And the sources are limited to voltage sources-no current sources. It only contains models of passive components, voltage sources, and logic gates. The listĪDS 1.00– This one seems to be of most value to students, and first-semester students at that, rather than working engineers. They are provided alphabetically along with the most notable benefits and drawbacks we uncovered. We’ve listed all the simulators we found -the good, the bad, and the ugly-that actually did perform circuit simulation in some fashion. Some of the most useful are optimized specific kinds of analog circuits such as those for power supplies or passive filters.

#ICIRCUIT CUSTOM ELEMENTS FREE#

We uncovered a handful of relatively powerful free packages that seemingly have few strings attached.

In one case, we tried a simulator that not only wouldn’t allow saving, but also posted publicly any circuits created by users on the free service.įortunately, not all free simulators suffer from such drawbacks. There may also be limitations on saving your work. Usually the free version has far fewer device models built in than the paid version. Nevertheless, we’ve included these simulators on our list if they still function-they may be enough if the goal is just to get a quick idea of how a circuit topology behaves.Īnother class of free simulator is actually a stripped-down variant of a program offered for sale.

#ICIRCUIT CUSTOM ELEMENTS UPDATE#

It’s easy to find simulators whose last update predates the invention of the iPhone.Īcademic simulators also tend to support only basic generic device models forget about probing any part-number-specific behaviors. A number of programs do, in fact, perform analog circuit simulation but were created by university researchers who seem to have lost interest in supporting them.

Other packages labeled as circuit simulators are, in fact, just schematic capture programs augmented with some printed circuit board layout facilities. We came up with 30 packages and online apps that seemed to offer benefits of use in actual circuit work.Ī few overall impressions: Sometimes open-source simulators mentioned in older blog posts have just disappeared. To help find the most useful packages from amongst the sea of online debris, we surveyed the field of free circuit simulators mentioned in posts and forums. It particularly excels in modeling high-power circuits. is among the more powerful free analog simulators. The LTspice program from Analog Devices Inc.
