In this paper, compact circuit models for spintronic devices have been developed by manipulating the underlying physical equations. We have simulated, via circuit simulation: 1) the magnetization dynamics governed by the Landau-Lifshitz-Gilbert (LLG) equation and 2) the spin transport physics governed by the spin drift-diffusion equation. The models have been validated using numerical and analytical solutions of the LLG equation and the spin drift-diffusion equations, respectively. Simulations of an all-spin logic device demonstrate the applications of the developed models in device and circuit simulation.
