Question 1.
What is clock skew?
Show hintHide hint
Think about how timing differences can affect data capture.
Question 2.
Name one technique used to minimize clock skew.
Show hintHide hint
Consider methods used in distributing clock signals.
3Question 3.
What is clock skew?
- Delay in signal propagation
- Difference in clock signal arrival times
- The periodicity of clock pulses
Show hintHide hint
Focus on the timing aspect of clock signals.
4Question 4.
True or False: Clock tree synthesis can help reduce clock skew.
- True
- False
Show hintHide hint
Remember the function of clock tree synthesis.
Question 5.
You have a distributed network of clock signals among flip-flops, and you observe a delay of 3 ns in some parts. How would you assess and fix this issue to improve timing?
Show hintHide hint
Look into restructuring your clock paths.
Question 6.
Given a design with significant clock skew leading to timing violations, outline the steps you would take to optimize the skew without compromising the overall circuit design.
Show hintHide hint
Think about both placement and routing as factors in your optimization strategy.
