    I think built in self test is used to test memory and connection in circuit
    memory BIST
    LOGIC BIST

    just for example , we made micro controller circuit . If decoder circuit in microcontroller is faulty , how does circuit detect fault by self checking that decoder is faulty ?

    I think we need test vector and we have to check out that all connection are correct

    but confused how we will do ?
