Abstract

Data Path Direct Access Test, DPDAT, supportsefficient structural test of targeted datapath blocksusing existing non-datapath DFT features inconjunction with architectural transparency alreadypresent in surrounding datapath blocks. This newDFT technique allows ATPG patterns generated atlogic block levels to be applied at the full chipwithout expensive DFT overhead. The results ofinvestigating feasibility on Intel® Pentium® 4 showexistence of these natural transparent paths, lowarea overhead and high fault coverage usingsequential ATPG techniques under DPDAT.
