Re: "Elmer - You seem concerned that the entire package must be tested, trace for trace at full rated speed. I think that's somewhat dopey at the least. If the memory chips are individually certified, and the circuit board certifies, and the cpu certifies, a minimal package certification should be all that is required. The path width sounds like an unnecessary distraction to me." Do you mean the whole system or do you mean the processor when you say package? If you mean the processor then I say yes it must be tested at full frequency provided you wish to ship the low DPM levels required by most systems vendors. If your customers are willing to accept higher defect levels then you can skip the fullspeed tests. I don't think either AMD or Intel skip these tests because their customers demand them. Attempts to guarantee at speed performance by means of SPC or other indirect methods are possible but they don't work to the DPM levels required today. EP
