Abstract:
A method for scanning a partially functional chip. The method may include applying a failed core map to the partially functional chip, bypassing at least one failed core scan chain, based on contents of the failed core map. The method may also include performing comparisons of scan status information to the failed core map and inhibiting movement of scan data of at least one failed core, based on results of the comparisons.
