Boundary-scan: Built to last? panel position

IEEE 1149.1 standard has been used extensively by the board test community to date. However, the nature of the circuits that are being tested is changing rapidly and significantly. In light of these changes and others the boundary scan technology will not likely survive long term. Higher levels of integration in silicon devices, increases in board density, and platform performance constraints will also play a role. Finally, the ever increasing customer quality expectations (at lower costs, by the way) will likely add nails to the coffin as well. That all being said some limited usage is expected to continue on lower density PCB´s and non-performance critical 10 interfaces for some time yet.
