Description: A new low-power (LP) scan-based built-in selftest
(BIST) technique is proposed based on weighted pseudorandom
test pattern generation and reseeding. A new LP scan
architecture is proposed, which supports both pseudorandom
testing and deterministic BIST. During the pseudorandom testing
phase, an LP weighted random test pattern generation scheme
is proposed by disabling a part of scan chains.
