![]() For circuit optimization (minimization of a cost function), ASCO is configured and run. For digital simulations (via VHDL) the program FreeHDL is used. The supported file formats as well as usage information can be found on the manpage of qucsconv.ĩ) Additionally, the GUI steers other EDA tools. It can be extended by the user.ħ) The attenuator synthesis application can be used to design various types of passive attenuators.Ĩ) The command line conversion program tool is used by the GUI to import and export datasets, netlists and schematics from and to other CAD/EDA software. microstrips, coaxial cables).Ħ) The component library manager holds models for real life devices (e.g. SPICE netlists, or Touchstone files).Ĥ) The filter synthesis application can be used to design various types of filters.ĥ) The transmission line calculator can be used to design and analyze different types of transmission lines (e.g. It takes a netlist, checks it for errors, performs the required simulation actions, and finally produces a dataset.ģ) The text editor is used to display netlists and simulation logging information, and to edit files included by certain components (e.g. ![]() QUCS is actually a collection of different modules and each has a different function.ġ) The GUI is used to create schematics, setup simulations, display simulation results, writing VHDL code, etc.Ģ) The analog simulator is a command line program which is run by the GUI in order to simulate the schematic which you previously setup. Once installed you will find QUCS in the applications-> Education-> menu in case of ubuntu or you can type qucs in the command terminal. Or you can do it the hard way, download the QUCS file from and execute the following commands.Ĭhange into the source directory: $ cd qucs-Ĭonfigure the source package for your system: $. In Ubuntu qucs is available in the Ubuntu software center. In a debian based system qucs can be installed by issuing the command The outputs of these analysis can be expressed in various forms like Smith-Chart, Cartesian, Tabular, Polar, Smith-Polar combination, 3D-Cartesian, Locus Curve, Timing Diagram and Truth Table. DC, AC, S-parameter, Harmonic Balance analysis, noise analysis, etc. The software aims to support all kinds of circuit simulation types, e.g. QUCS is a circuit simulator with graphical user interface (GUI). ![]() Though still in development process it is very stable and effective, but of course there are things missing here and there, we will see what all qucs can do and cannot do. Quite Universal Circuit Simulator (Qucs) is a open source electronics circuit simulator software released under GPL, and is still in development process. But very recently I came to know about Quite Universal Circuit Simulator. I knew about some circuit simulators but the experiences that I had when I first tried one was not so good. Though it was simple it was difficult and I burned out many components. I have spent upto 3 weeks trying to figure out what was wrong with a circuit I made. If the design is wrong then there is no point in proceeding further, also most electronic components get damaged even if a very small mistake is made in designing the circuit. Circuit designing and debugging can be one heck of a job. Unlike most other hobbies like philately or numismatics there are a lot of things that an electronic hobbyist must know before getting his hands wet, otherwise things can get real messy and you may loose a lot of money. Electronics is a hobby for many, and it can be really expensive. But making an electronic circuit ‘work’ is even tougher. Life can be a bit tough without these gadgets. We use many electronic gadgets in our daily life.
