Electronic CAO tools are actually efficient and helpful for circuit designers separately in many domains : RF, low-signal circuits, electromagnetic, power circuits...Nevertheless, they have to take in account the reconciliation in the future of complex electronic commands boards associated to power energy converters system integrated on closer structures, and the upsurge of electric/electromagnetic couplings in a large frequency band . In this context, we present a global modelling methodology for EMC considerations on Electronic Printed Circuit Board (PCB) and some applications for oriented EMC simulations. In a first time, we optimise an electrical models library dedicated to the simulations of EMC emissions of digital integrated component, including all the passives and actives elements used for EMC measurement test benches developed. In a second time, we propose global studies with the aid of time-domain simulator(Saber, MawellSpice) to realise a virtual experiment of considered phenomena. Results of measured and simulated EMC signals on test PCB with single digital component are presented to analyse and conclude about different contributions of the electrical elements of the board with their electrical environment for EMC comportment and characteristics.
