Abstract
This invention generates the random seed patterns using simple, low-area overhead digital circuitry on-chip. This circuit is implemented as a finite state machine whose states are the seeds as contrasted to storing the seeds in the prior art. These seeds are used to control pseudo-random pattern generation for built-in self-tests. This invention provides a large reduction in chip area in comparison with storing seeds on-chip or off-chip.
