BIST (Built-In Self Test)

BIST (Built-In Self Test)


BIST (Built-In Self Test) is a mechanism that permits a machine to test itself. Engineers design BISTs to meet requirements such as high reliability and lower repair cycle times, or constraints such as limited technician accessibility and cost of testing during manufacture. The main purpose of BIST is to reduce the complexity, which decreases the cost and reduces reliance upon external test equipment.
