Abstract: Disclosed is an improved approach to implement clock alignments between a test subject and its corresponding controller device. Phase locking is performed for the clocks between the test subject and controller device via a training sequence to obtain the appropriate alignment(s). Alignment logic is included on both the testchip and the controller device to implement alignment.
