Question 1

What does t_setup represent?

Time input must be stable before clock edge
Time output must be stable before clock edge
Time after clock edge is irrelevant

💡 Hint: Think about which timing condition is crucial for data reliability.

Question 2

True or False: A D-Flip-Flop can change its output at any time during the clock signal.

True
False

💡 Hint: Consider how their timing behavior differs.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

An FPGA design requires a D-Flip-Flop to work reliably at a frequency of 200 MHz. What is the maximum clock period, and how do the timing measures (t_setup, t_hold, t_CQ) need to relate to it?

💡 Hint: Calculate clock period from frequency and think about timing measure limits.

Challenge 2 Hard

In a circuit, if the setup time is 5 ns and hold time is 2 ns, what would happen if the output changes in 3 ns after the clock edge?

💡 Hint: Assess how timing requirements impact data integrity.
