Challenge Problems
Push your limits with challenges.
Question 1
Design a small digital circuit that utilizes a scan chain. Explain how you would implement test vectors and what faults you would expect to catch.
💡 Hint: Think about how each part of the circuit interacts with the test patterns.
Question 2
Consider a scenario where a scan chain fails to detect certain delayed signals in high-speed applications. How might you enhance fault coverage in this situation?
💡 Hint: Reflect on the limitations of scan chains in complex systems and consider supplementary strategies.
