An examination of PRPG selection approaches for large, industrial designs

A study for selecting effective pseudo-random pattern generators (PRPGs) for large industrial designs is undertaken. For the PRPG selection process, guidance from a set of ISCAS benchmark circuits is initially sought. The set of benchmark circuits used is shown to be ineffective in providing material guidance. The alternative of PRPG selection through actual design experimentation is examined and its weaknesses identified and outlined. A brief DFT analysis is outlined to indicate the importance of early PRPG selection.
