Sadly, late breaking (post silicon or just late in development process) bugs aren't generally particularly more exciting in terms of debugging than earlier ones - other than the urgency/annoyance and rarity, of course.

They do tend to be 10x as annoying to debug though. Not more difficult - just tedious - especially because you often end up triaging what turns out to be somebody else's bug (i.e. a checker on your block fails, so you need to trace it back to somebody else, and often they also trace it outwards to somebody else).

And this is where using it as a class example gets really difficult - even people on the design team are specialists in their own blocks. Giving students all the knowledge they'd need to debug a problem would be incredibly difficult.
