  The precession of a ferromagnet leads to the injection of spin current and
heat into an adjacent non-magnetic material. Besides, spin-orbit entanglement
causes an additional charge current injection. Such a device has been recently
proposed where a quantum-spin hall insulator (QSHI) in proximity to a
ferromagnetic insulator (FI) and superconductor (SC) leads to the pumping of
charge, spin, and heat. Here we build a circuit-compatible Verilog-A-based
compact model for the QSHI-FI-SC device capable of generating two topologically
robust modes enabling the device operation. Our model also captures the
dependence on the ferromagnetic precision, drain voltage, and temperature with
an excellent (> 99%) accuracy.
