Its good design practice to have a non reflective board design, however i
would like to understand the nature of the failure caused by the reflections.
One failure mechanism is double triggering, but assuming the reflections acuse
an overvoltage (over the power supply value, or under ground value) BUT not ringing through
thetriggering point, how can a chip be affected by this ringing....? Does it make the input
buffer levels lower (hey hey hey, its spikes, short term influence, doesn't it???).
Any help, article and/or any pointer is appreciated.!!
regards, yehuda
