      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.
