Quite Universal Circuit Simulator is an integrated circuit simulator. By using this free program, you will be able to setup a circuit through QUCS´ graphical user interface (GUI). To do that, you can select eeach required component from the wide library the program has. You´ll be able to choose between resistors, grounds, capacitors, inductors, sub-circuits, transformers, amplifiers, isolators, circulators and a lot more components, grouped under the "lumped components" category. You can also select different sources, probes, transmission lines, non-linear components, verilog devices, digital components and more. To place any of the components, you´ll only need to drag it from the list and drop it onto the circuit. You can adjust different values for each component by right-clicking oon it and choosing the appropriate settings. When done, you can simulate a large-signal, small-signal and noise behavior of the circuit. Simulation results will be displayed in a graph. This program supports all types of circuits, such as DC, AC, S-parameter, Harmonic Balance analysis and Noise analysis.
