Challenge Problems

Push your limits with challenges.

Question 1

Given a layout that passes LVS verification, describe a series of steps to perform post-layout simulations and determine the impact of parasitics on delay.

💡 Hint: Focus on the comparisons made in the simulation.

Question 2

Consider a scenario where a layout is not matching the schematic according to the LVS report. What might be the ramifications of proceeding to fabrication without corrections?

💡 Hint: Think about the consequences of unmet design requirements.
