Do you know how many ENIAC vacuum tubes were replaced every day during its heyday? What did it teach us about Test, or Design-For-Test? Did Eldred really invent the stuck-at fault model in 1959? Is 99.999% fault cover all it?s cracked up to be or are we fooling ourselves? Are we better off with 115% or even 80%? Where did Design-For-Test come from? Where is it now? Where?s it heading? Is it true that boundary scan is the panacea of test? What are all these new Joint Test Action Groups -- Internal, System and compact? Are they boondoggles, or are they serious?
