Jim - Re: "How long does it take to reasonably debug a chip after first silicon?" That depends on the CPU - and the DESIGN STAFF ! Since the K7 is a "new core", AMD is clearly having problems getting it production worthy. That should be reassuring to AMD's customers ! In retrospect, it indicates that AMD's design approach is heavily flawed - especially in light of the LATE & S L O W Kmart 63 "ramp" ! Intel's approach - using the P6 core over and over - has allowed them greater opportunities for "quick" success. Mendocino was essentially production worthy on first silicon. Dixon was also - but was tweaked for lower power at high speed. Coppermine first silicon has very minimal problems on first silicon - and a minor metal mask tweak will fix that problem. Chip sets are another story. Camino was a real learning experience - not so much from a logic design standpoint, but from an electrical interface to a very high speed, poorly characterized DRDRAM bus structure - with all the attendant problems of transmission line issues.
