Block model of microcontroller for electromagnetic immunity simulation

This paper presents an approach to constructing the immunity model of the microcontroller based on functional blocks. The microcontroller is treated as an assembly of functional blocks and propagation paths of electromagnetic interference. Function blocks are I/Os and cores where the interference propagation paths are referred to interconnections such as packages and on-chip power distribution network (PDN). The model structure and its building blocks are proposed. Their construction methods are presented.
