Editor?s note:
Will it or won?t it? The 1999 IEEE 1149.4 Standard for a Mixed-Signal Test Bus is on the cusp of industrial acceptance, but it?s not clear whether industry will pick it up. This study, by two leading European research institutes, delves into the details of hardware implementation and, in so doing, contributes to the growing literature on this topic.
