Qucs 0.0.3 has been released.
The Qucs project (Qucs = Qt universal circuit simulator) today
announced the immediate availability of Qucs 0.0.3, a Qt-based
advanced and powerful microwave circuit simulator for GNU/Linux and
Qucs, including all its libraries and its applications, is available
for free 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 microwave circuits, a
simulator, which is able to simulate the small- and large signal
behaviour of microwave circuits. The results can be shown on a
special presentation page in different formats (rect, polar, smith,
Compiling Qucs 0.0.3
The complete source code for Qucs 0.0.3 may be freely
downloaded. Instructions on compiling and installing Qucs 0.0.3 are
included in the software archive. Only Qt-Libs >= 3.1 and the glibc
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
Qucs comes now with translations into Polish and Romanian. Many new
components are available in the GUI as well as new operations,
i.e. undo/redo functionality, alignment, resizing of paintings and an
application setting dialog. The subcircuit support has been improved,
rectangle diagrams are able to scale logarithmically and a graphs
drawing style can be set. Many minor improvements and overall
bug-fixing has been done.
Speed of the S-parameter and its noise simulation has been increased.
There are now some more microstrip components available, e.g gap,
open, corner, mitered bend, step and coupled lines. A MOSFET, JFET
and a BJT implementation has been done; S-parameter file components
(touchstone), subcircuits, logarithmic sweeps and an additional noise
analysis are now available. Also some more documentation has been
the Qucs team.
