Abstract

Traditional yield enhancement efforts have long relied onmemory bitmapping techniques. With the industrymarching toward system-on-a-chip technology, theimportance of logic products has increased exponentially.This necessitates the development of innovativetechniques to perform logic yield enhancement. In thispaper, the authors present a novel technique that can beused to perform logic yield enhancement. The paperconcentrates on logic bitmapping at Texas Instruments.Results obtained from a few production samples of agraphics processor are also presented.
