Question 1

What is the primary purpose of post-layout simulations?

  • To verify LVS
  • To assess real-world performance with parasitics
  • To create a layout

💡 Hint: Think about the stage of design we are discussing.

Question 2

True or False: LVS verification ensures that all schematic devices are present in the layout.

  • True
  • False

💡 Hint: Consider what happens when you run LVS.

Challenge Problems

Push your limits with challenges.

Question 1

Given a schematic with typical values for an inverter, calculate expected propagation delay factoring in parasitic capacitance. If observed delays are double the expected, suggest potential layout adjustments.

💡 Hint: Use the relationship between capacitance, resistance, and time delay.

Question 2

You encounter LVS mismatches in a layout indicating that several transistors are unrecognized. Outline a strategy to debug this issue effectively.

💡 Hint: Error messages will guide you to specific mismatched areas.
