Qucs-S: Quite universal circuit simulator with SPICE
Qucs-S provides a fancy graphical user interface for a number of popular circuit simulation engines. Qucs-S contains libraries for schematic capture, visualization and components. The following simulation kernels are supported:
- Ngspice (recommended)
- Xyce
- SpiceOpus
- Qucsator (non-spice)
See the https://ra3xdh.github.io/ for more details. Qucs-S is based on original Qucs code: https://github.com/Qucs/qucs
Donation
Qucs-S accepts donation using Boosty platform: https://boosty.to/qucs_s
Build instructions
Use CMake to build Qucs-S. Install all necessary dependencies: GCC, Qt, and SPICE
(optional). Install ngspice that is not needed for build, but serves as the simulation kernel.
Dependencies
Ubuntu
sudo apt-get install ngspice build-essential git cmake qtbase5-dev qttools5-dev libqt5svg5-dev
OpenSUSE Tumbleweed
sudo zypper install ngspice git cmake libqt5-qtbase-devel libqt5-qttools-devel libqt5-qtsvg-devel
Compiling
Qt5
Then clone this git repository and execute in the top directory:
mkdir builddir
cd builddir
cmake .. -DCMAKE_INSTALL_PREFIX=/your_install_prefix/
make
make install
Where /your_install_prefix/ is desired installation directory. Substitute any
desire path (for example $HOME/qucs-s) here. You may omit this option and
installation steps. Default installation directory will be /usr/local if
CMAKE_INSTALL_PREFIX is not defined.
Qt6
Since v1.0.1 Qucs-S supports build with Qt6. Set the QT_DIR environment variable
to tell CMake use the Qt6. For example use the following command sequence for Ubuntu-22.04
export QT_DIR=/usr/lib/x86_64-linux-gnu/cmake/Qt6
cmake .. -DCMAKE_INSTALL_PREFIX=/your_install_prefix/
Running
Then run qucs-s executable to launch the application:
cd /your_installation prefix/bin
./qucs-s
