Qucs 0.0.15 has been released.

Qucs 0.0.15 has been released.

The Qucs project (Qucs = Quite Universal Circuit Simulator) today
announced the immediate availability of Qucs 0.0.15, 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>.


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 0.0.15

The complete source code for Qucs 0.0.15 may be freely
downloaded. Instructions on compiling and installing Qucs 0.0.15 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 new translations into Arabic and Czech,
model libraries for PMOSFETs, NMOSFETs, regulators, varistors and
ideal components, and many new primitive components such as EPFL-EKV
NMOS/PMOS V2.6, rectangular waveguide, HICUM L0 v1.2, HICUM L2 v3.23,
photodiode, digital buffer, microstrip radial stub, phototransistor,
RLCG transmission line and numerous new digital primitives. Passing
parameters to Verilog-HDL and VHDL subcircuits and typed generic
parameters of VHDL files are now supported as well as arbitrary in/out
signals. Simulation time for digital files (Verilog and VHDL) are now
stored in an additional configuration file and the import dialog has
been replaced by a complete import/export frontend for the
Qucs-Converter command line tool. US letter formats for schematic
frame have been added. The build system now implements an additional
install step for MacOSX and the appropriate icons.

In the analogue simulation core global nodes (e.g. subst!) have been
introduced, property references inside the same instance of a
component and variables in constant parameter simulation boxes are
allowed. A noise figure property has been added to the amplifier
model and the matrix power operation is available in the equation
solver. The Qucs-Converter command line tool allows now to translate
existing HICUM models into library elements as well as the translation
of polynomial C's and L's and F, H, E and G polynomial SPICE sources.


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!
