Qucs 0.0.11 has been released. The Qucs project (Qucs = Quite Universal Circuit Simulator) today announced the immediate availability of Qucs 0.0.11, a Qt-based advanced and powerful microwave circuit simulator for GNU/Linux and other UNIXes. Qucs, including all its libraries and its applications, is available as free (as in speech) software under Open Source licenses. Qucs can be obtained in source code from <http://sourceforge.net/projects/qucs>. Features Qucs provides a GUI based on Qt for setting up electrical and electronic circuitry, a simulator, which is able to simulate the small- and large signal as well as the noise behaviour of these circuits. The results can be shown on a special presentation page in different formats (rect, polar, smith, tabular, 3d-cartesian, locus and polar-smith combinations). Pure digital simulations are also supported. Compiling Qucs 0.0.11 The complete source code for Qucs 0.0.11 may be freely downloaded. Instructions on compiling and installing Qucs 0.0.11 are included in the software archive. Only Qt-Libs >= 3.1 (but < 4.x) and the glibc are required. About Qucs Qucs is an independent project of only a few developers, translators, etc, collaborating over the Internet to create and freely distribute a sophisticated, customizable and stable microwave circuit simulator. For enhancing the development speed we are looking for more developers, who want to support the Qucs Project. Changes in this release The new release comes with two new translations into Czech and Catalan, subcircuit parameters and equations in subcircuits. The tabular scrollbar can now be moved directly with the mouse cursor dragging and painting and handling of graphics has been much improved at zoom factors != 1. Some new components have been added including the device models for HICUM L2 v2.1 and FBH HBT. The simulation backend now supports the knee current in the diode model and the excess phase of the BJT during transient analysis. Subcircuit parameters have been implemented which can be sweep parameters and constants as well as equation variables. Equation variables can now also be used in component properties and input parameters of components in equations. The model for the non-ideal microstrip junction has been implemented. There are three new components, i.e. twisted pair, 4-terminal transmission line and a bondwire. Moreover ADMS XML scripts have been implemented for Verilog-AMS device models. Two example device models have been added: HICUM L2 v2.1 and FBH HBT. Thanks A lot of thanks go to the translators and to the supportive user responses so far encouraging us to improve the software. We couldn't have done it without you! So long, the Qucs team. |
