Abstract

According to an embodiment of the present invention, a computer-implemented method for testing a microelectronic chip is described. The method may include dividing, via a processor running a scanning engine, a plurality of sections of the microelectronic chip. Each of the plurality of sections includes at least two latch sets in at least one scan chain. The method may further include determining, via the processor, based on the dividing, whether each of the plurality of sections fail a data test. The determining comprises interleaving the plurality of sections by scanning, via the processor, an alternating latch set from each scan chain in a first section, and scanning an alternating latch set from each scan chain in a second section.
