Title: Low-cost design for register file testability

Abstract: A self-test module for use in an electronic device includes a test controller and a memory. The memory is configured to receive test vectors from the test controller. A comparator is configured to receive the test data from the memory via an output data path. A strobing buffer is located in the output data path between an output from the memory and an input to the comparator. The strobing buffer is configured to selectively enable the test vectors to propagate from the memory output to the comparator input.
