1 Scope
This part of IEC 62433 specifies macro-models for ICs 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 model can also be used for modelling an IC-die, a functional block and
an Intellectual Property block (IP).
The ICEM-CE 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 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 standard gives general data, which can be implemented in different formats or
languages such as IBIS, IMIC, SPICE, VHDL-AMS and Verilog. SPICE is however chosen
as default simulation environment to cover all the conducted emissions.
This standard also specifies requirements for information that shall be incorporated
in each ICEM-CE model or component part of the model for model circulation, but description
syntax is not within the scope of this standard.
