Finite Element Method [FEM]

It is common for people doing simulations to make a measurement of a similar set up to validate the simulation. The real issue is whether the tool user understands the problem well enough to capture the important features, and whether the user understands the tool well enough to use it correctly.

The electronic industry has embraced simulation to address several complex design challenges, but reliability is still mostly dealt with best design practices and tested with prototypes. In this article, we present how modeling and simulation approaches can help designers perform virtual prototyping and uncover reliability issues especially EOS/ESD before going for physical prototypes.

Heat flow analysis for semiconductor ESD situations can be approximated to one dimension, and then captured with a generalized Ohm’s Law using a complex impedance. Methods can include time-dependent electrothermal pulses and feedback due to self-heating, with solutions readily carried out on any desktop computer.

Electromagnetic compatibility (EMC) is the ability of electronic equipment to function properly without interference from noise sources and without causing disturbances to other electronic equipment. This article will help the reader understand the modes of electrical noise propagation, how fields interact, and the methods of testing for EMC, helping to provide the basis for designing low-emissions, low-susceptibility electronic equipment.

Are you just getting into software simulation and feeling a little overwhelmed with all the new jargon? This brief article will explain some of the most common terms used in the very exciting world of EMC/Signal Integrity simulation software, all in one location.
