BIST

特許 権利維持 A built-in self-test (BIST) or built-in test (BIT) is a mechanism that permits a machine to test itself. Engineers design BISTs to meet requirements such as: high reliability lower repair cycle times or constraints such as: limited technician accessibility cost of testing during manufacture The main purpose[citation needed] of BIST is to reduce the complexity, and thereby decrease the cost and reduce reliance upon external (pattern-programmed) test equipment.
