Numerical simulation of an electromagnetic aggression on a FACT component and investigation on package effect

This paper presents different approaches made by numerical simulation to study the behavior of electronic components and the effect of their package, when submitted to an ElectroMagnetic (EM) aggression. The simulations are performed using several codes: DESSIS-ISE, SPICE, ELF3D and ELFI3S. The EM susceptibility of an input buffer (FACT technology) is investigated. Continuous Wave (CW) type aggressions with different frequencies and amplitudes are simulated. The results emphasize differences between component simulation tools. However, the most significant differences are observed between EM interactions at the component levels and at the package level. In particular, a noise filtering process due to the package appears at sufficiently high frequencies.
