James, ideally it is the best for 100% fault coverage. Is it possible? Even the pricy LSI tester can only cover x% of logic and y% of memory block, etc. etc. Plus the redundancy most likely in his case is a requirements, 100% is a costly and time consuming proposition. Agree, design need to put an handle on it at day one, it just impossible to do it as after thoughts. My 1.92 cents (devalue everyday :-(.

(Smells like Hog Wash if I remember correctly!) :-) If you line produces 10% bad device (90% yield which is pretty bad depending on what you are building) and your ICT coverage is only 90% you will have a 1% rate of failure going out the door.
