Challenge Problems
Push your limits with advanced challenges
Design a circuit that could potentially include stuck-at faults and outline a testing strategy using scan chains.
💡 Hint: Think about handling each node in your test design.
Consider a complex IC that implemented scan chains. Discuss the potential consequences if delay faults are overlooked during testing.
💡 Hint: Reflect on what timing inconsistencies could lead to in synchronous systems.
