BIST: a test a diagnosis methodology for complex, high reliability electronics systems

A test and diagnosis methodology that is based on built-in self-test(BIST) is defined and described. A BIST solution based on a maintainable system architecture is described that includes the technology, and tools needed for the development of chip, board, and system BIST. This architecture is based on the IEEE 1149.5 MTM-Bus at the backplane level and the IEEE 1149.1 (JTAG) Boundary Scan Architecture at the chip level.
