Developing a universal exchange format for Integrated Circuit Emission Model - Conducted Emissions

Abstract

A new international standard proposal (IEC 62433-2 Edition 2.0) is in progress. The main purpose of the standard is to provide an Integrated Circuit Emission Model -Conducted Emission (ICEM-CE) along with a data exchange format. It is known that the existing ICEM-CE information is closely linked to the supplier of the model or simulation software used to generate the model information, rendering extremely difficult its exchange between suppliers, customers, EDA tool vendors, academics, etc. This paper describes a universal exchange format for ICEM-CE. The format is based on the well-known eXtensible Markup Language format, which is both machine and human readable. As an illustrative example, it is applied on an Atmega88 microcontroller: the model is extracted by the manufacturer, Atmel, and is exchanged with an academic partner, INSA, and an industrial partner, Valeo. The exchange proves fruitful and the model was easily deployable to predict conducted emission noise.

“…As for these matters, various research has been reported in the past years [11][12][13]. Reference [14] gives an overview of the EMC research focusing on chip-level.…”

“…Hyun Ho Park, et al generated a macro model of the timing controller chip for running pseudo H pattern data from transistor level simulation and is used to estimate the power switching current on the printed circuit board (PCB) [23]. Abhishek Ramanujan, et al designed a common interchange format for ICEM based on the well-known extensible markup language format and applied to Atmega88 microcontrollers [13]. Modeling methods for PCB and components with both chips and packages were published in [24] and [25], in order to calculate PCB power noise generated by the switching chip.…”
