“…Since coupling of multiple converter noises forms the system noise, the effect of such multinoise coupling on system noise prediction is investigated. An ever-increasing concern in electronic literature is EMC/EMI issue, [6] - [8]. The fast-switching transistors and vast number of electronic goods with has led to concerns and guideline over their generation of EMI problems, [9].…”

In this paper, a stochastic analysis method is proposed for extraction and evaluation of power distribution map (PDM) in system printed circuit board (PCB). This is conducted based on some high level data including placement and routing geometry, power distribution network (PDN), component package parasitic, and voltage regulator module (VRM). A simple model for supply current of two constituent blocks of electronic systems is analytically extracted. The worst-case simultaneous operation of all consumers are considered for PDM extraction. The approach is applied to a specific designed and fabricated mixed signal board. PDM is beneficial in the placement process of decoupling capacitance or noisy components in an optimum and right location. Also, the proposed approach can be considered as a verification step of PCB design flow and be applicable before routing only based on the placement data of components of the system. This enables the designer to predict the upcoming problems in layout and hastens the process of design verification.

“…along with revolutionary ideas including Internet of Things, Smart Cities, and Industry 4.0 has affiliated the today's generation with modern electronics more than ever [1]. Hence, electromagnetic compatibility/interference (EMC/EMI) issues has acquired an ever increasing importance in electronics literature [2][3][4][5]. On one hand, modern electronics features highdensity, high-frequency and low-voltage circuitry, thereby entailing inherently low-level immunity to electromagnetic interferences (EMI) [6].…”

<p> In this paper we derive a method to determine the worst-case radiated immunity of a given printed circuit board (PCB) layout, whose benefits are threefold. First, the worst-case performance could be used as a reference to compare the radiated immunity of two competing, schematically-identical-yet-electromagnetically-distinct layouts. Second, it could be used as a criterion to determine whether a given layout is able to observe the particular requirements of a given electromagnetic compatibility (EMC) standard. And finally, since this method is element-independent, it requires no modelling for complex circuit elements such as non-linear elements, logic gates, processors, etc. to interact with electromagnetic interference (EMI). Our method determines how much power could be delivered to the non-linear circuit elements of the PCB by an EMI under a worst-case scenario. This could be done, either for the entire PCB, or for specific parts and elements of interest, such as sensitive elements, logic gates, microprocessors, etc. While a fully analytical approach with a closed-form solution is developed for the former, the latter could be obtained through an analytical derivation followed by numerical maximization. These methods would enable the rapid and straightforward evaluation of the designs’ immunity at any stage, resulting in saving cost and time. </p>
