Testing of assembled printed circuit boards and other products based on highly complex digital integrated circuits and high-density, surface-mounting assembly techniques has become extremely difficult due to test access limitations. IEEE 1149.1 is particularly important to industry as many other standards including IEEE 1500, IEEE 1532, IEEE 1687, and IEEE 1838, rely on this standard and its defined Test Access Port (TAP) to provide access to and control of features built into integrated circuits.
These standards are beneficial to, and should be of interest to:
