Qucs-S is a circuit simulation program with Qt-based GUI

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 instruments for schematic capture, visualization and provides differents passive and active components including device library. 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, Flex, Bison 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 flex bison

OpenSUSE Tumbleweed

sudo zypper install ngspice git cmake libqt5-qtbase-devel libqt5-qttools-devel libqt5-qtsvg-devel flex bison

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
