Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider an electronic system that implements BIST. If the fault coverage is reported at 85%, what does this suggest about the number of detectable faults?

💡 Hint: Think about what a percentage represents in terms of whole system faults.

Challenge 2 Hard

Analyze why BIST may have limitations regarding unknown or complex faults. Provide a real-world example where this could be critical.

💡 Hint: Consider scenarios where new technologies might introduce unforeseen faults.
