Well, yeah, I&#x27;m just saying it wasn&#x27;t a picnic at 40nm or 90nm, either. It didn&#x27;t go from a walk in the park to a nightmare at 28nm.<p>Also I believe all the bugs in TFA are logical bugs where the circuit would have misbehaved in a logical simulation, not the kind where the circuit &quot;flips zeros to ones&quot; or vice versa because of physical implementation issues. In this sense advanced nodes make things worse only indirectly by enabling larger, more complex designs.
