Practice Questions

Test your understanding with targeted questions

Question 1 Easy

What is the main difference between a latch and a flip-flop?

💡 Hint: Think about when the outputs change in relation to the clock.

Question 2 Easy

Define setup time in relation to flip-flops.

💡 Hint: Consider how long D must be 'ready' before the clock signal changes.

Question 1

What does a D-Flip-Flop do?

Stores data during clock high
Changes output only on clock edges
Has no memory

💡 Hint: Focus on how the flip-flop relates to the clock signal.

Question 2

True or False: A latch retains data when the clock signal is low.

True
False

💡 Hint: Consider when the output changes and retains data.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a D-Flip-Flop that can operate at a clock frequency of 1 GHz. What considerations must you take regarding timing parameters?

💡 Hint: Remember, frequency means how often the clock ticks, and relate it to time.

Challenge 2 Hard

Simulate a D-Latch behavior in a software tool. Identify the clock settings that lead to metastability.

💡 Hint: Try to change D closer to the clock edge in your test setup to observe the effects.
