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.
Supports spice simulators.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install qucs-spice, simply use the following command:
