Challenge Problems

Push your limits with challenges.

Question 1

Design a NAND gate and run both pre-layout and post-layout simulations. Document your findings, including any changes in delay and discuss the impact of the parasitics observed.

💡 Hint: Pay attention to the measurements and how they change after accounting for parasitics.

Question 2

What challenges did you face during parasitic extraction, and how did those challenges affect your understanding of the post-layout simulation process?

💡 Hint: Reflect on real-world applications of parasitic extraction versus theoretical knowledge.
