Question 1.
What does Scan-In (SI) allow in a scan chain?
Show hintHide hint
Think about the entry point of data.
Question 2.
Name one component of a scan chain.
Show hintHide hint
Consider the components we discussed.
3Question 3.
What is the purpose of Scan-Out (SO) in a scan chain?
- To shift data into the chain
- To transfer test results out
- To control operational mode
Show hintHide hint
Think about where results go after testing.
4Question 4.

- True
- False
Show hintHide hint
Recall our discussion on testing time.
Question 5.

Show hintHide hint
Consider how changing length affects time and coverage.
Question 6.
Analyze the power versus performance trade-off when integrating multiplexers into a scan chain.
Show hintHide hint
Consider how increased features can affect overall design efficiency.
