GB/T 44807.3-2025 EMC IC modelling—Part 3:Models of integrated circuits for EMI behavioural simulation—Radiated emissions modelling(ICEM-RE)

Scope

This document specifies a method for deriving a macro model of the radiation emission level of integrated circuits (ICs). This model is commonly referred to as the Integrated Circuit Emission Model - Radiation Emission (ICEM-RE). The model is designed to be used for modeling the entire IC when the measured or simulated data cannot be directly imported into the simulation tool, regardless of whether there is knowledge of the relevant packaging, functional blocks, and intellectual property (IP) blocks of analog and digital ICs (input/output pins, digital cores, and power supplies). The IC macro model proposed in this document will be imported into three-dimensional electromagnetic simulation tools in order to: ● Predict the near-field radiation emission of the IC; ● Evaluate the impact of radiation emission on neighboring ICs, cables, transmission lines, etc. This document includes two main parts: ● The first part is an electrical description of the elements of the ICEM-RE macro model; ● The second part proposes a universal data exchange format called REML based on XML, which encodes the ICEM-RE in a more practical and universal form for simulating emission.
