Abstract :
This paper presents a study addressing the challenge of interfacing automatic test equipment (ATE) with on-chip decompression logic deployed by system-on-chip designs or modular decompression environments. The ability of the proposed scheme to improve the encoding bandwidth by reusing groups of scan chains for test data storage has been measured on industrial designs and is reported herein.
