Qucs-S offers Windows and Linux binaries. It merges the power of SPICE and the simplicity of the Qucs GUI. The purpose of the Qucs-S subproject is to use free SPICE circuit simulation kernels with the Qucs GUI. Qucs-S is a spin-off of the Qucs cross-platform circuit simulator. The Windows binary is stand-alone (no installer). (graphical user interface, circuit simulator, PCB layout, and numerical data processing etc.) Currently QucsStudio supports Windows only. It’s meant to be a test project to create a complete development environment for electrical engineers. The simulation engine is even a complete new creation. QucsStudio is mainly a circuit simulator that has evolved out of the project Qucs, but isn’t compatible with it. QucsStudio is free but does not seem to be open source. QucsStudio a free, non-commercial, powerful circuit simulator. Qucs offers Windows, macOS, and Linux binaries. After the simulation has finished you can add and view the simulation results along with the circuit schematic or on a presentation page. It enables you to setup a circuit with a graphical user interface (GUI) and simulate the large-signal, small-signal and noise behavior of the circuit. ![]() Qucs (Quite Universal Circuit Simulator) is the original application. To my knowledge there are three main facets, each with their own strengths, Qucs, QucsStudio, and Qucs-S, with not a lot of interoperability between them: The Qucs-based eco-sphere is rather fragmented and somewhat confusing in my opinion. Posted in Software Hacks Tagged simulation, SPICE Post said: “Qucs and QucsStudio (not mentioned) are actually different programs…”Īctually there is a bit more to the story. But there were a few on the list we had not heard of and maybe you’ll find something new there, too. For example, Falstad has a great mixed mode that can even include an AVR microprocessor. While the capsule descriptions are nice, you may want to dig in a little on the ones you are most interested in. While the list includes TI’s Tina, it doesn’t seem to mention that TI also provides a free version of PSpice which is a very popular professional product. Proteus doesn’t let you save or print unless you pay. For example, DCAClab only provides an NPN bipolar transistor model. Many of the trial versions were very limited. Old favorites like Falstad (which is apparently known as Circuit Sims) and TinkerCAD made the list. Some are branded versions of commercial products (like Tina) or were made free after selling for higher price tags (like MicroCap 12). ![]() Some of those are just trial or student versions of paid products. There are also some lesser-known products. There are several on the list that you’ve probably heard of before like GNUCap and LTspice. If you are selecting one or don’t like the one you are currently using, it is well worth the time to review. But there’s a problem: how do you select from so many alternatives? We were interested in ’s review earlier this year of 30 free circuit simulators. Keep in mind, however, that a capacitor stores and discharges electric energy, whereas a resistor dissipates it.We live in a time where great software is available with the click of a mouse, often for free or - at least - low cost. As a result, they have the same unit, the ohm. The quantity \(X_C\) is analogous to resistance in a dc circuit in the sense that both quantities are a ratio of a voltage to a current.
