scope:
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.
