Question 1.
What increases the complexity of a design when implementing scan chains?
Show hintHide hint
Think about what components are added.
Question 2.
What is a benefit of using test pattern compression?
Show hintHide hint
What does compression generally do?
3Question 3.
What does increased design complexity refer to in scan chain implementation?
- Increase in area
- Decrease in performance
- Both A and B
Show hintHide hint
Consider the impacts of adding components.
4Question 4.
True or False: Test pattern compression only reduces test time and not power consumption.
- True
- False
Show hintHide hint
Think about compression and efficiency.
Question 5.
Given a scenario of implementing a scan chain in a large SoC, identify potential power optimization strategies and justify their importance.
Show hintHide hint
Focus on the techniques that limit unnecessary power use.
Question 6.
Discuss how one could balance the trade-offs between the increased area due to scan chains and the benefits they provide, including an example.
Show hintHide hint
Weigh both pros and cons carefully.
