Qucs-S is a free open source integrated circuit simulator for Linux and Windows. It is released under the open source GPL-2.0 license. This is a spin-off of the popular circuit simulator Quite Universal Circuit Simulator (QUCS). I am using the SPICE circuit simulation kernel in the Qucs GUI. Supports all Qucs component types and simulations
Direct support for SPICE models from component datasheets. Supported SPICE components are RCL, BJT, MOSFET, JFET, MESFET, switch, source and RCL defined by equation, transmission line. It also supports SPICE model cards, SPICE sections, parametric circuits, SPICE postprocessors, and more.
