Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Your circuit contains a critical path with a delay of 40 ns and a setup time of 8 ns. What is the maximum frequency of your clock signal?

💡 Hint: Make sure to add the critical path delay and setup time together before computing frequency.

Challenge 2 Hard

If the critical path can be optimized to reduce its delay to 30 ns, what is the new maximum operating frequency?

💡 Hint: Reduced delay leads to increased frequency—calculate accordingly.
