Yes, although just having the faulty hardware isn't enough. They also have to use the tools to show that it behaves incorrectly, which is surely a lot more work than just following the book would have been. That is the part that is easily reproducible. The student already knows how, so in a few minutes he can set it up in front of the prof and show him. The prof needn't do anything other than watch for a few mins.

If more of these cases crop up then you should get suspicious, but you also need to consider the impact of giving a student the wrong chip and expecting them to succeed! I think Blackstone's Ratio should apply here personally
