Abstract :
The paper presents a review of the most important phenomena that determine the signal integrity and EMC on the signal traces for the PCB equipped with digital circuits. The aim of this paper is to highlight the effects of variation of design parameters, signal integrity and EMC field. For all of the mentioned phenomena the mathematical models are specified. These models can be used in order to characterize the PCB signal traces and the way in which these models can be implemented in Matlab program. The Matlab simulated results and other electronics circuit simulator results (Pspice, Omega+) are compared. Based on this comparison, some observations about model performances and limitations can be done. Using these results, the paper analyses the effect that appears in signal integrity assurance and EMC, based on variation of some signal traces parameters. The conclusions of this paper are recommendation for signal traces design when digital circuits are used.
