BIST systems was in the U.S.'s Minuteman Missile. Using an internal computer to control the testing reduced the weight of cables and connectors for testing. The Minuteman was one of the first major weapons systems to field a permanently installed computer-controlled self-test. Specializations There are several specialized versions of BIST which are differentiated according to what they do or how they are implemented: Programmable built-in self-test (pBIST) Memory built-in self-test (mBIST) - e.g. with the Marinescu algorithm Logic built-in self-test (LBIST) Analog and mixed-signal built-in self-test (AMBIST) Continuous built-in self-test (CBIST, C-BIT) Event-driven built-in self-test, such as the BIST done to an aircraft's systems after the aircraft lands. Periodic built-in self-test (C-BIT/P-BIT) Interrupt-driven built-in self-test (IBIST) or user/operator-initiated built-in self-test (I-BIT, or O-BIT) Power-up built-in self-test (PupBIST, P-BIT) Automatic built-in self-test (ABIST) See also Built-in test equipment Logic built-in self-test Embedded system System engineering Safety engineering Watchdog timer References External links Hardware Diagnostic Self Tests BIST for Analog Weenies - A Brief general overview of the capabilities and benefits of BIST by Analog Devices.
