Challenge Problems

Push your limits with challenges.

Question 1

You have extracted parasitic capacitance of 5pF and resistance of 10Ω for a section of your layout. Analyze how these parameters can impact the signal transition time and what design changes could be proposed to mitigate the delays.

💡 Hint: Consider the implications of RC time constants on transitions.

Question 2

In your design, you run a post-layout timing analysis and discover that the setup time violations occur at the output of a flip-flop. What steps can be taken to address these timing violations?

💡 Hint: Explore how placement can influence setup times.
