Question 1.
What is a scan chain?
Show hintHide hint
Think about how circuits can be tested effectively.
Question 2.
What technique is used to reduce power during testing?
Show hintHide hint
Consider how parts of a circuit can be turned off.
3Question 3.
What is the purpose of scan chain partitioning?
- To increase the length of the scan chain
- To split the scan chain into smaller parts for parallel testing
- To connect more flip-flops
Show hintHide hint
Think about how to make the testing process faster.
4Question 4.
True or False: Power gating can help in reducing the area of a circuit.
- True
- False
Show hintHide hint
Consider what each technique is targeted at.
Question 5.
Discuss the trade-offs involved in using redundant flip-flops versus maintaining a minimal design. What are the implications for testing and overall circuit performance?
Show hintHide hint
Consider the balance between thoroughness and simplicity.
Question 6.
Create a testing strategy for a circuit using both static and dynamic scan length optimization techniques. What factors will influence your decisions?
Show hintHide hint
Consider how different testing environments might impact your strategy.
