A behavioral model for a magnetoresistive spin valve device implemented in Verilog-A is presented. The model realizes the complete static, single-domain magnetic hysteresis response as well as a damped transient response based on Landau-Lifshitz-Gilbert dynamics. The model will facilitate the design and analysis of complex spintronic or hybrid spintronic-electronic circuits in a simulation environment that is familiar to most circuit designers. The utility of the spin valve model is demonstrated in the analysis of a MRAM cell.
