Vi passo un estratto molto interessante di un articolo che ho trovato su http://www.nasdaq.com/asp/quotes_news.asp?selected=ATYT&symbol=NVDA%60&symbol=INTC%60&symbol=CREAF%60&symbol=ATYT%60&symbol=OVER%60&symbol=ATVI%60&symbol=AMD%60&symbol=HAS%60&textpath=20030514%5C200305140902CTXBIZ37086236%2Ehtm&cdtime=05%2F14%2F2003+9%3A02AM
ATI's visual processing unit (VPU) has more than 200 million transistors of digital logic. A design of this size and complexity requires not only extremely high stuck-at fault coverage, but also thorough testing for delay-related defects, the preponderant defect type in 0.13 micron process geometries and below. Using basic scan methods, excellent delay test requires up to 6X more tester time than required for stuck-at faults, which already is at an unacceptable cost of test.
Che si stia parlando dei famigerati R390/R420 ?
Ciao
