What is BS EN 62433-4 - Conducted immunity model (ICIM-CI) about?
BS EN 62433-4 is the fourth part of an international standard used for EMC IC modelling.
BS EN 62433-4 specifies a flow for deriving a macro-model to allow the simulation of the conducted immunity levels of an integrated circuit (IC). This model is commonly called Integrated Circuit Immunity Model – Conducted Immunity, ICIM-CI. It is intended to be used for predicting the levels of immunity to conduct RF disturbances applied on IC pins.
In order to evaluate the immunity threshold of an electronic device, this macro-model will be inserted in an electrical circuit simulation tool. This macro-model can be used to model both analogue and digital ICs (input/output, digital core and supply). This macro-model does not take into account the non-linear effects of the IC. The added value of ICIM-CI is that it could also be used for immunity prediction at the board and system level through simulations.
Note: This part of IEC 62433 contains two main parts:
- The electrical description of ICIM-CI macro-model elements
- A universal data exchange format called CIML based on XML. This format allows ICIM-CI to be encoded in a more useable and generic form for immunity simulation
Who is BS EN 62433-4 - Conducted immunity model (ICIM-CI) for?
BS EN 62433-4on EMC IC modelling is useful for:
- Manufacturers of electronic devices
- Manufacturers of automotive parts
- Manufacturers of circuit boards
- Electronic engineers
Why should you use BS EN 62433-4 - Conducted immunity model (ICIM-CI)?
EMC IC model is software that contains electromagnetic compatibility (EMC) of integrated circuits. This model helps in covering both parasitic emission and susceptibility to radio-frequency interference.
By using BS EN 62433-4, you can determine the immunity behaviour of the integrated circuits (IC). The model data is exchanged in the Conducted Immunity Markup Language (CIML) that helps in understanding the ICIM-CI model.
With the help of BS EN 62433-4, you can identify the ICIM-CI macro-model parameters by measuring the RF immunity behaviour. By applying BS EN 62433-4 you can forecast electromagnetic immunity at the application level of the Conducted immunity model (ICIM-CI). This helps in evaluating the immunity of the integrated circuits which results in manufacturing improving the quality of Conducted immunity model (ICIM-CI).
