"Cheating" implies something sinister. Far more likely, they just missed it. Modern CPUs are at the very edge of what humans can design and build. Hundreds of verification engineers try to make sure they work. Not one of them will have a whole picture of the entire machine in their head, or really understand all of its requirements. The very best, hardest working, most diligent and dedicated teams will still ship a CPU with bugs. Perfection is simply not possible in this domain.
