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
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
