Go to File → Application Settings menu to configure the language and appearance of Qucs.Qucs (Quite Universal Circuit Simulator) is one of the best circuit simulator applications, an open source graphical software implemented in C++ around Qt and designed from the offset to act as an integrated circuit simulator for a vast selection of operating systems. Right above it you can find the menu bar and the toolbars. The large area on the right hand side is the schematic area. Usually, the projects folder will be empty if you are using Qucs for the first time. On the left hand side you will find the Projects folder opened, as shown in Fig. Therefore, depending on your system’s language settings, the Qucs GUI appears in different languages. Once the software has been successfully installed on your system you can start it by issuing the # qucs command, or by clicking the appropriate icon on your start menu or desktop. And for circuit optimisations ASCO (see ) is configured and run. For digital simulations (via VHDL) the program FreeHDL (see ) is used. The supported file formats as well as usage information can be found on the home page of Qucs.Īdditionally, the GUI steers other EDA tools. 8: Components tabĬommand line conversion program.The conversion tool is used by the GUI to import and export datasets, netlists and schematics from and to other CAD/EDA software. 7: New empty project has been created Fig. The user can extend it with additional components.Īttenuator synthesis application.The program can be used to design various types of passive attenuators. The component library manager holds models for real-life devices, such as transistors, diodes, bridges and op-amps. This can be used to design and analyse different types of transmission lines (examples: micro-strips, coaxial cables).Ĭomponent library. This is used to display netlists and simulation logging information, and also to edit files included by certain components (like Spice netlists or Touchstone files).įilter synthesis application.The program can be used to design various types of filters. It takes a netlist, checks it for errors, performs the required simulation actions and finally produces a dataset. GUI.It is used to create schematics, set up simulations, display simulation results and to write VHDL code.īack-end analogue simulator.The analogue simulator is a command line program which is run by the GUI in order to simulate the schematic that you previously setup. Qucs consists of several stand-alone programs interacting with each other through the GUI, such as: While some examples have been included in this story to demonstrate some of the abilities of Qucs.įeatures and their functions Fig. It also provides semiconductor-based components and models such as PMOSFETs, MOSFETs, op-amps, diodes and many more. Qucs comes with a huge array of components and models including HICUM, BSIM2, BSIM3 and BSIM6 to list a few. 3: Data display with different kinds of data representations (diagrams) and data markers Fig. 1: Combined schematic and data visualisation Fig. It has been programmed for usage in the Qucs project but may also be used by other applications. It takes a network list in a certain format as input and outputs a Qucs dataset. Qucsator, the simulation back-end, is a command-line circuit simulator.

Qucs can also import existing Spice models for use in your simulations. Apart from representation in DC, AC, S-parameter, noise and transient analysis, mathematical equations and use of a sub-circuit hierarchy (with parameterised sub-circuits) are also available. The Qucs GUI is well advanced and allows setting up schematics and presenting simulation results in various types of diagrams.

The software aims to support most kinds of circuit simulation like DC, AC, S-parameter, harmonic balance analysis and noise analysis to name a few. Post simulation, you can view the simulation results on a presentation page or window. Qucs is an integrated circuit simulator that enables you to set up a circuit with its intuitive graphical user interface (GUI) and simulate the small-signal, large-signal and noise behaviour of the circuit. It also supports a growing list of analogue and digital components as well as Spice sub-circuits, which makes it easier to work with. Qucs is much simpler to use and handle than other circuit simulators like gEDA or PSpice. It can simulate circuit behaviour, and supports pure digital simulations using VHDL and/or Verilog languages. MuthaĪn open source electronics circuit simulator software released under GPL, Quite Universal Circuit Simulator (Qucs) provides the user with capabilities to set up a circuit with a graphical user interface.
