NEN-EN-IEC 62433-2 specifies macro-models for an Integrated Circuit (IC) to simulate conducted electromagnetic emissions on a printed circuit board. The model is commonly called Integrated Circuit Emission Model - Conducted Emission (ICEM-CE). The ICEM-CE macro-model can also be used for modelling an IC-die, a functional block and an Intellectual Property (IP) block. The ICEM-CE macro-model can be used to model both digital and analogue ICs. Basically, conducted emissions have two origins: • conducted emissions through power supply terminals and ground reference structures; • conducted emissions through input/output (I/O) terminals. The ICEM-CE macro-model addresses those two types of origins in a single approach. This standard defines structures and components of the macro-model for EMI simulation taking into account the IC’s internal activities. This part of IEC 62433 has two main parts: • the first is the electrical description of ICEM-CE macro-model elements along with the specific requirements for information. • the second part proposes a universal data exchange format called CEML based on XML. This format allows encoding the ICEM-CE in a more useable and generic form for simulating the conducted emissions.
