Abstract
A method for testing an integrated circuit to reduce peak power problems during scan capture mode is presented. The method comprises programming a respective duration of a first time window for each of a plurality of cores and a cache on the integrated circuit. It further comprises counting the number of pulses of a first clock signal during the first time window for each of the plurality of cores and the cache. Subsequently, the method comprises staggering capture pulses to the plurality of cores and the cache by generating pulses of a second clock signal for each of the plurality of cores and the cache during a respective second time window, wherein the number of pulses generated is based on the respective number of first clock signal pulses counted for each of the plurality of cores and the cache.
