The way I see it, the cube effect at 3% amounts to a degradation of less than 10% of the lifetime, which is almost meaningless because the statistical expectation for realistic failure time is probably wider than that. Do you know what the MTBF is for the parts? A few years ago, at 0.5u and 0.6u processes, I would expect MTBF to be 100 years or so. Even if it has dropped to 30 years, this is WAY beyond the useful lifetime of the system. Other components will fail before that. The system will become so obsolete in 10 years it is JUNK because it is OLD - not because the processor is junk. INTC-based PCs that are 10 years old are also JUNK - because of the same reason. I have over 20 years of hardware experience - almost all in IC design, including some lifetime analysis a few years back. My experience says that your argument that a 100 mv change in the power turns the parts to junk IS THE REAL JUNK. Drop it. You are wrong. Ed Miller Senior Design Engineer
