sch-rnd-sim 1.0.5-1ubuntu1 (armhf binary) in ubuntu noble

 Circuit simulation that can export and execute SPICE (ngspice) in the
 background and save or present the results. Works both from the GUI
 (with dialogs for configuring simulation setups, presenting plots and
 data in the same dialog) and from CLI (with actions using existing
 configuration, saving output data to a computer readable file).
