As voltage margins for power rails continue to decrease, end-to-end power integrity modeling is already difficult without having to be concerned if all of your simulation models are correct. System designers typically assume that all of the vendor models are correct. So, what does an engineer do if one of the ASIC die models needed for a power integrity simulation is incorrect? 

SIJ technical editor Eric Bogatin reflects on reflections… “Do corners in traces on circuit boards cause reflections? Of course, they do. Do the reflections cause problems and should you worry? ….it depends.” Read on to see what he means.
