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.

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

Publication "Qucs: An introduction to the new simulation and compact device modelling features implemented in release 0.0.19/0.0.19Src2 of the popular GPL circuit simulator.",Įnabled automatic generation and deployment of Doxygen source code documentation. Reverse breakdown is modeled by an exponential increase in the reverse diode current and is determined by the parameters Bv (reverse breakdown voltage) and Ibv (current at reverse breakdown voltage).Latest News Latest stable release: 0.0.19 The nominal temperature at which these parameters were measured is Tnom. The following table shows some of components supported by the simulator for each kind of simulations. The temperature dependence of the saturation current is defined by the parameters Eg, the energy bandgap and Xti, the saturation current temperature exponent. Charge storage effects are modeled by a transit time, Tt, and a nonlinear depletion layer capacitance which is determined by the parameters Cj0 (zero-bias junction capacitance), Vj (junction potential), and M (grading coefficient). The dc characteristics of the diode are determined by the parameters Is (saturation current) and N (emission coefficient). In this case, the LED is based on the model parameters for the PN Junction Diode, which are documented in the appropriate section of the technical documentation: You do need to understand how the models work though. If you look at the entries in the existing 'LEDs' library (LEDS.lib in subfolder Qucs\share\qucs\library of my Windows Qucs installation) you will see how these are defined.
