Challenge Problems

Push your limits with challenges.

Question 1

Given a circuit with a reported pre-layout propagation delay of 2 ns, analyze how an increase in parasitic capacitance of 5 fF might affect this metric based on the formula of P_dynamic.

💡 Hint: Use the relationship between capacitance, resistance, and delay to find the new propagation delay.

Question 2

If an LVS check gives an error stating 'Mismatch in Number of Devices' with your schematic showing 10 devices and your layout showing 12, describe the steps you would take to troubleshoot this error.

💡 Hint: Check each step methodically and refer to the LVS report details for guidance.
