in built-in self-test (bist) techniques, storing all the circuit outputs on chip is not possible, but the circuit output can be compressed to form a signature that will later be compared to the golden signature (of the good circuit) to detect faults. since this compression is lossy, there is always a possibility that a faulty output also generates the same signature as the golden signature and the faults cannot be detected. this condition is called error masking or aliasing. bist is accomplished with a multiple-input signature register (misr or msr), which is a type of lfsr. a standard lfsr has a single xor or xnor gate, where the input of the gate is connected to several "taps" and the output is connected to the input of the first flip-flop. a misr has the same structure, but the input to every flip-flop is fed through an xor/xnor gate. for example, a 4-bit misr has a 4-bit parallel output and a 4-bit parallel input. the input of the first flip-flop is xor/xnord with parallel input bit zero and the "taps". every other flip-flop input is xor/xnord with the preceding flip-flop output and the corresponding parallel input bit. consequently, the next state of the misr depends on the last several states opposed to just the current state. therefore, a misr will always generate the same golden signature given that the input sequence is the same every time.
