Qucs: overview, status and roadmap

This talk presents Qucs (Quite Universal Circuit Simulator) features, the current status of development and the project roadmap.

Qucs is an integrated circuit simulator. The graphical user interface (GUI) is used for schematic capture and visualization of simulation results. It can simulate the large-signal, small-signal and noise behavior of the circuit. The software aims to support all kinds of circuit simulation types such as DC, AC, transient, S-parameter, noise analysis, harmonic balance analysis. Digital simulation and circuit optimization are integrated into the GUI and powered by other open-source tools (Icarus-Verilog, freeHDL, ASCO). Besides the library of components it also includes tools for the design of active and passive filters, transmission lines, attenuators and matching circuits. Interfaces for Matlab/Octave and Python are also available.

The talk will provide an overview of the features and available tools along with a selection of examples. It will present the latest developments including: ongoing migration towards the latest Qt framework; new features related to the “turn-key” Verilog-A (ADMS) model compiler as well as support for other simulation engines (Ngspice, Xyce).
