Model development plus a range of compact and behavioural device modelling and post simulation data analysis tools that have become centralįeatures in this open source software package of surprising power and utility. Manipulation, Equation-Defined Device (EDD) modelling, Radio Frequency Equation-Defined Device (RFEDD) simulation and Verilog-A synthesised The recent versions of the software include code for algebraic equation Made to improve the device modelling tools distributed with Qucs. Including for example, transient simulation, device parameter sweep capabilities and single tone Harmonic Balance simulation, making Qucsįunctionality comparable to SPICE at low frequencies and significantly extended at high frequencies. In the years following 2003 the Qucs Development team has added a number of additional simulation facilities, Provided users with a relatively stable, flexible and functional circuit simulation package which is particularly suited to Since it was first release under the General Public License (GPL) in 2003 Qucs has Qucs was originally written as an RF and microwaveĮngineering design tool which provided features not found in SPICE, like S parameter simulation, two and multiport small signal ACĬircuit analysis and RF network synthesis. The project also aims toĪdd additional model development tools to those currently available in Qucs-0.0.18. Version of Qucs while attempting to combine some of the best features of other GPL circuit simulation packages. It addresses a number of problems observed with the current ReferenceQt® is a registered trademark of Digia.Following the release of Qucs-0.0.18 in August 2014 the Qucs Development Team considered in detail a number of possible directions thatįuture versions of the software could take. It is free for free programmers and users! LicenseQucs is released under the GPL license and so To be successfully compiled and run on Windows, Solaris, GNU/Linux OS using the standard autotools with no specialĮffort to support other operating systems. Operating SystemsQucs is currently developed under the ![]() Schematics can be found here which demonstrate some of theĪbilities of Qucs, and many more examples are provided with the Semiconductor based components and models such as OpAmps,ĭiodes, MOSFETs, PMOSFETs and many more. Models including HICUM, BSIM2, BSIM3 and BSIM6 can be compiledĪnd loaded into the simulator. Qucs comes with an array of components and models. Quality example schematics, tutorials for the website and lots Just need help with programming, it also needs graphics, high Project, and will always welcome offers of help. While Qucs is well developed, we still strive to improve the QucsĬan also import existing SPICE models for use in your Hierarchy (with parameterised subcircuits) are available. Is possible, mathematical equations and use of a subcircuit DC, AC, S-parameter, noise and transient analysis Schematics and presenting simulation results in various types The Qucs GUI is well advanced and allows setting up Programmed for usage in the Qucs project but may also be used It takes a network list in a certainįormat as input and outputs a Qucs dataset. Qucsator, the simulation backend, is a command lineĬircuit simulator.S-parameter, Harmonic Balance analysis, noise analysis, Support all kinds of circuit simulation types, e.g. Qucs, briefly for Quite Universal Circuit Simulator, is aĬircuit simulator with graphical user interface (GUI).The simulation results on a presentation page or window. After that simulation has finished you can view Qucs is an integrated circuit simulator which means you areĪble to setup a circuit with a graphical user interface (GUI)Īnd simulate the large-signal, small-signal and noise behaviour Take a look at the screenshots to get a feel for what it So far Qucs is not yet finished, but it is already Previous news items What's Qucs?Qucs stands for Quite Universal Circuit Other paths using QSettings (~/.qucs/qucsrc is nowĪdded beginnings of m-code transient solver New implementation of matrix calculations usingĪdded option for changing the home directory and Updated manuals, developers and FAQ webpages Released Mac OSX installer (10.7 to 10.9), ASCO included.įor FreeHDL, Verilog-A, users are better served using a ![]() Updated package for Ubuntu 14.04 (Trusty) and 14.10 (Utopic), Released installer fo Mac OSX 10.6 (Intel 64 bit) (ASCO included).
