QUCS - Quite Universal Circuit Simulator

Qucs is an integrated circuit simulator which means you are able to setup a circuit with a graphical user interface (GUI) and simulate the large-signal, small-signal and noise behaviour of the circuit. After that simulation has finished you can view the simulation results on a presentation page or window.

Resources

Currently Supported Platforms

  • GNU/Linux
  • Darwin/OS X
  • FreeBSD
  • Windows

Source Download and Compilation

The source code is available as a tarball for stable releases and Git repository clone for development.

The release tarball can be downloaded from: http://sourceforge.net/projects/qucs/files/qucs/. Compilation and install from tarball is expected to work as follows (see dependencies below):

tar xvfz qucs[version].tar.gz
cd qucs[version]
./configure
make install

For the lates code in development, clone from one of the Git repositories (the first is updated more frequently):

git clone git://github.com/Qucs/qucs.git
git clone git://git.code.sf.net/p/qucs/git

For test and development qucs-test is provided as a Git submodule. To download the submodule either:

  • clone submodules recursively:
    • git clone --recursive [repository]
  • or after cloning, do:
    • git submodule init
    • git submodule update

Compilation and installation depends on the operation system. See below for an example.

Compile instructions Linux (Debian/Ubuntu)

First make sure you have all dependencies installed:

sudo apt-get install build-essential
sudo apt-get install libqt4-dev libqt4-qt3support
sudo apt-get install automake libtool gperf flex bison

The ADMS package is necessary. Please download the latest tarball and follow the install instructions. HavingadmsXml on the path should be sufficient.

To build the manuals and user documentation further dependencies are needed. Please check the qucs-doc/README file.

Bootstrap and build everything (after cloning):

cd qucs
./bootstrap
./configure
make
sudo make install

Compile Qucs GUI tools only:

cd qucs
[./bootstrap] #if not executed in the top level
./configure
make
sudo make install

Compile qucs-core tools only:

cd qucs-core
[./bootstrap] #if not executed in the top level
./configure
make
sudo make install

Compile qucs-doc documentation only:

cd qucs-doc
[./bootstrap] #if not executed in the top level
./configure
make
sudo make install

Testing can be executed at the top level with:

make check

Note:

  • Qucs will be installed to /usr/local by default. You may override this by passing --prefix=[some location] to the ./configure script.

  • ADMS should be installed e.g. from a released tarball (>= 2.3.0). To use a different admsXml pass the option --with-admsxml=[path/to/]anotherAdmsXml to `./configure'.

  • The LaTex documentation compilation in qucs-doc can be skipped passing --disable-doc to the top level configure script.

  • Consider the output of ./configure --help for more and definitive build options.

Binary Installation

Some of the platform specific pre-compile binary packages containing installers can be found at https://sourceforge.net/projects/qucs/files/qucs-binary/.
