Qucs-S is a circuit simulation program based on Qucs circuit simulator.The "S" letter indicates SPICE. The purpose of the Qucs-S project is to use free circuit simulation kernels (Ngspice, Qucsator, Xyce) with the unified GUI based on Qt6 toolkit. It merges the power of SPICE and the simplicity of the Qucs GUI. Qucs-S is not a simulator by itself, but it requires to use an external simulation backend with it. Qucs-S allows to use the following open-source simulation kernels: - Ngspice is recommended to use. Ngspice is powerful mixed-level/mixed-signal circuit simulator. Not included in this package, available in the cad/ng-spice package. -QucsatorRF for RF and microwave circuits design. It provides advanced models for such devices microstrip lines and waveguides. QucsatorRF is not SPICE compatible. Included in this package. - XYCE and SpiceOpus are other simulators that can be used from QUCS-S. Not included in this package.
