My end customer has now asked for a full MTBF for the Design. Firstly do Intel have MTTF / FIT data for their parts? I was just hoping for transistor counts etc as many processor vendors supply these as they show a compliance with Mores Law, but I cant find that data for b...

Finally, we’ll discuss how reliability testing is modernizing to fit today’s environments. What is software reliability testing and how has it evolved? Software reliability testing has its roots in reliability engineering, a statistical branch of systems engineering focused on designing and building ...

Therefore, if the mean time to fail (MTTF) for a device is known, it is possible to predict when the hardware component fail.Historical data about mechanical and electrical components fit the so-called bathtub curve illustrated in the following figure....
