EMC IC modelling – Part 2: Models of integrated circuits for EMI behavioural simulation – Conducted emissions modelling (ICEM-CE) - Edition 2.0
 N 62433-2

Annotation

This part of IEC 62433 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
