The Qucs cross-platform circuit simulator is a spin-off of Qucs. The letter S stands for the SPICE engine, which performs all simulations within the software. The Qucs subproject's goal is to integrate free SPICE circuit simulation kernels into the Qucs GUI. It combines SPICE's capability with the Qucs GUI's simplicity. Qucs utilizes its own SPICE incompatible simulation...

    If you can get s parameter model you can use that. There are also generic transformer and coupled line models so long as you've got a way of characterising it you should be able to model it. https://sourceforge.net/projects/qucs/. Source: over 3 years ago
