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
Qucs-S accepts donation using Boosty platform: https://boosty.to/qucs_s
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.
sudo apt-get install ngspice build-essential git cmake qtbase5-dev qttools5-dev libqt5svg5-dev flex bison gperf dos2unix
sudo zypper install ngspice git cmake libqt5-qtbase-devel libqt5-qttools-devel libqt5-qtsvg-devel flex bison gperf dos2unix
Then clone this git repository and execute in the top directory:
git submodule init
git submodule update
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.
Since v1.0.1 Qucs-S supports build with Qt6. Set the WITH_QT6
flag to tell CMake use the Qt6.
For example use the following command sequence for Ubuntu-22.04
cmake .. -DWITH_QT6=ON -DCMAKE_INSTALL_PREFIX=/your_install_prefix/
Then run qucs-s
executable to launch the application:
cd /your_installation prefix/bin
./qucs-s
Clangd looks for compile_commands.json
file in parent folders of the file it processes.
compile_commands.json
should be generated along with other build configuration files
when you run cmake
as part of building routine:
mkdir builddir
cd builddir
cmake .. -DCMAKE_INSTALL_PREFIX=/your_install_prefix/
If compile_commands.json
is already there, create a symbolic link to it from project root dir:
cd project_root
ln -s ./builddir/compile_commands.json compile_commands.json
It may take some time to index files at first run. Clangd configuration is in .clangd
file.
