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
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>.
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
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.
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.
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!
