This paper describes a new test pattern generator to increase fault coverage and a test pattern transferring method to reduce test time without large hardware overhead in the BIST structure. The new pattern generator uses a 2-level LFSR scheme in which inputs are varied and controlled by the counter output. An asynchronous internal clock generated by an internal ring-oscillator is used for fast test pattern transfer into the scan chain. The new 2-level LFSR scheme is verified by the HITEC fault simulator.
