Process variability is becoming more problematic as transistor density increases, both in planar chips and in heterogeneous advanced packages.
On the basis of sheer numbers, there are many more things that can wrong. “If you have a chip with 50 billion transistors, then there are 50 places where a one-in-a-billion event can happen,” said Rob Aitken, a Synopsys fellow.
And if Intel’s...
