,Today, the design of IC, subsystems and |*fGG?}  
systems dealing with electromagnetic problems `(q+@#)  
(EMC) is often based on insufficient data and on =xw) [  
assumptions of design constraints. TC<_I0jCh  
The term EMC (Electromagnetic Compatibility) {}s7q|$

interference in electronic systems. Growing {3i.U028]  
complexity, denser design and higher clock rates dK#:io[Nz

EMC is not commonly accepted in microelectronic !eMz;GZ  
design. Microelectronic designers have ^}a..@|%W  
the opinion that EMC has to do with electrical and %S. _3`A

Therefore, design under EMC-constraints is a big VWj]X7v  
challenge and requires highly skilled engineek. -S"YEH9  
The high processing speeds and integration ^|5vmI'E  
densities lead to effects like reflections, crosstalk [O2xE037h`

as well as to electromagnetic radiation and Ovxs+mQ
