  • Patent number: 7512925
    Abstract: A system and method for reducing test time for loading and executing an architecture verification program for a system-on-a-chip (SoC) are provided. The mechanisms of the illustrative embodiments reorganize the scan chains of the SoC and provide an algorithm for organizing and pipelining architectural verification program (AVP) data for scanning into the reorganized scan chains. The scan chains are reorganized so as to align the scan cells for memory array data for each memory array across a plurality of scan chains. The scan chains are further reorganized so that each scan chain has unique AVP data, i.e. no scan chain has more than one memory array's information. The pipelining algorithm bundles data according to the length of the scan chain, the maximum size of the memory array data, and the position of the memory array's scan cells in the scan chains.
