In recent years, accumulators have been shown to be efficient pattern generators and response compactors for built-in self-test. Many circuits contain modules which can be configured as accumulators just by controlling these modules adequately. This paper presents algorithms that find all possible accumulator configurations in a circuit and optimize the control of the accumulators for fast test application or inexpensive test control implementation.
