Summary:
Abstract This paper proposes a software-related conducted electromagnetic interference (SW-cEMI) model reduction process for two-stage pipelined microcontroller (μC). This paper is based on a black-box transfer function (BBTF) cEMI model building technology and a new proposed decomposition method to reduce the BBTF model (rBBTF) to a reasonable model size. If the number of a μC s machine codes is N and the pipeline stage is p, the BBTF model size would be 2Np. The rBBTF method can reduce the size to 2Np. By the propose method, the simulation and estimation of the target μC s SW-cEMI behaviors become efficient without sacrificing much accuracy. Both of the measurement and simulation results are given to justify the proposed modeling method.
