IEC 62433-2-2017 EMC IC modelling – Part 2: Models of integrated circuits for EMI behavioural simulation – Conducted emissions modelling (ICEM-CE) (Edition 2.0)
Modèles de circuits intégrés pour la CEM – Partie 2: Modèles de circuits intégrés pour la simulation du comportement lors de perturbations électromagnétiques – Modélisation des émissions conduites (ICEM-CE) (Edition 2.0)
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 ?C 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
