Study on built-in self test technology based on the microprogramming
A design of built-in self test (BIST) in one control system based on the microprogramming is introduced. There are three kinds of micro instructions in the BIST system, and the linear feedback shift register (LFSR) is used as response signature analyzer is the BIST to compress the circuit′s signature. The flow graph of the running of microprogramming and principle of the BIST architecture in diagnose process is proposed. The design of BIST based on microprogramming has excellent capabilities to diagnosis and detect the fault,which can locate the fault of circuit on board accurately.
