Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You are tasked with designing a circuit using NAND and NOR gates for a specific application. Identify the pros and cons of using a NAND gate over a NOR gate in terms of layout and performance.

💡 Hint: Consider the typical use cases for both types of gates.

Challenge 2 Hard

After a DRC check, several violations arise from a layout that uses shared diffusion. Explain how these violations could be rectified while still maintaining area efficiency.

💡 Hint: Think about the design rules related to spacing and dimensioning.
