About this release

I am glad to present you the 0.0.24 release of Qucs-S an universal GUI for SPICE-compatible circuit simulation engines. Visit http://ra3xdh.github.io/ to learn more about Qucs-S.

New features of the 0.0.24

New simulation types

  • Added S-parameter simulation using Ngspice and Xyce backends; Ngspice>=37 requiered #84, #79
  • Added FFT analysis with Ngspice backend #88

GUI improvements

  • Implemented dark desktop theme support #66
  • Implemented manual setting of the X-axis markers postion #92
  • Added separate setting for schematic and application font

Qt5 support

  • Removed QtScript dependency (thanks @zergud) #77
  • Fixed Qt5.15 deprecation warnings #75

Component libraries

  • Added quartz crystal library (Crystal.lib); the quartz model is optimized for filter design;
  • Added TL431 device in Regulators library;

General bugfixes

  • Fixed crash on HB simulation with XYCE #28
  • Fixed empty path for working directory #86
  • Show error when schematic contains only DC simulation (no effect for Ngspice) #83
  • Fixed layout in arrow properties dialog #81
  • Fixed drag'n'drop operation from left dock to schematic
  • Fixed newlines in SPICE resitors #62
  • Fixed crash on Wayland #76

Documentation and examples

  • Added offline PDF tutorial; the link for old Qucs tutorial removed from Help menu #78
  • Added examples for new S-parameter and FFT simulations
  • Fixed distortion simulation example #83

Additional information

See also our presentation from MIXDES-2017 conference for more info about Qucs-S and its compact modelling features. You may download the Part 1 and Part2 from the ResearchGate.

Known issues

  • Parameter sweep doesn't work when using the Fourier simulation with XYCE backend #73
  • Ngspice netlister may produce duplicate .SUBCKT entry when using the same component from user and system library #82

Source code

Download the source code file qucs-s-0.0.24.tar.gz and build it with cmake to try new Qucs-S.

Linux

Windows

Windows portable package could be downloaded as zipped distribution. Unpack and launch qucs-s.exe from bin subdirectory. Ngspice requires a separate installation. There is two windows packages available:

  • qucs_s_win64_0_0_24.zip 64-bit (x86_64) portable Windows version;
  • qucs_s_win32_0_0_24.zip 32-bit (i686) portable Windows version;
