Software-related EMI model reduction for two-stage pipeline microcontroller

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 2N^p. The rBBTF method can reduce the size to 2N^p. 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.
