This paper is concerned with recent advances in Qucs-S/Ngspice/XSPICE modelling capabilities that improve model construction and simulation run time performance of Equation-Defined Devices using XSPICE model syntheses. Moreover, Equation-Defined Devices often promote a clearer understanding of the factors involved in the construction of complex compact semiconductor simulation models. It’s inherent interactive properties make it ideal for device and circuit modelling via Qucs schematics. Today, this component has become an established element for building experimental device simulation models. Enter under Graph Properties the following equation for S21: 2yvalue(output.Vb, 1.9e9) / uRF This can easily be understood, because this is the well known definition of S21: S21 output signal at R1 divided by the incident wave (u-RF / 2) But have a sharp look at the output voltage expression in the equation: You must use output.Vb. Some example schematics can be found here which demonstrate some of the abilities of Qucs, and many more examples are provided with the program.The Qucs Equation-Defined Device was introduce roughly ten years ago as a versatile behavioural simulation component for modelling the non-linear static and dynamic properties of passive components, semiconductor devices and IC macromodels. It also provides many semiconductor based components and models such as OpAmps, Diodes, MOSFETs, PMOSFETs and many more. Qucs comes with a huge array of components and models including HICUM, BSIM2, BSIM3, and soon BSIM6. Qucs doesn't just need help with programming, it also needs graphics, high quality example schematics, tutorials for the website and lots more. While Qucs is well developed, we still strive to improve the project, and will always welcome offers of help. Qucs can also import existing SPICE models for use in your simulations. DC, AC, S-parameter, noise and transient analysis is possible, mathematical equations and use of a subcircuit hierarchy (with parameterised subcircuits) are available.

The Qucs GUI is well advanced and allows setting up schematics and presenting simulation results in various types of diagrams. 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 backend, is a command line circuit simulator. DC, AC, S-parameter, Harmonic Balance analysis, noise analysis, etc.

QUCS ADD TO EQUATION SIMULATOR

Qucs, briefly for Quite Universal Circuit Simulator, is a circuit simulator with graphical user interface (GUI). Introduction The following sections are meant to give an overview about what the Qucs software can be used for and how it is used to achieve this. After that simulation has finished you can view the simulation results on a presentation page or window.

Qucs is an integrated circuit simulator which means you are able to setup a circuit with a graphical user interface (GUI) and simulate the large-signal, small-signal and noise behaviour of the circuit.

Simulation of the DC characteristics of a diode modelled with a B source pwl function diode series resistor set at 1e-3 Ohm B source example 2: Simulation of the properties of a high power. Take a look at the screenshots to get a feel for what it can do. Qucs equations usage with ngspice and Xyce Manipulating simulation data with algebraic measurement scripts Qucs Equation-Defined Device (EDD) models. So far Qucs is not yet finished, but it is already packed with features. Qucs stands for Quite Universal Circuit Simulator. Hi, This happens if Export is set to GUIonly. The software aims to support all kinds of circuit simulation types, e.g. It seems that sometimes depending on the export setting the symbol results in the equations subscripting and then they dont work. Qucs is a circuit simulator with graphical user interface.
