Some approaches have been reported, based on Verilog-A model, however, these results were limited only to primitive logic gates [10, 11] or logic circuits with regular structure such as logic-array structure [12]. In [8], a design flow for MTJ/MOS-hybrid random-logic LSI with irregular structure has been reported, however, since the switching behavior of
MTJ/MOS-hybrid logic gates are evaluated using pre-created lookup tables in this flow, the effect of stochastic behavior of MTJ devices cannot be considered for performance evaluation.
