Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If parasitic capacitance is doubled in a circuit, and the original propagation delay was 2 ns, estimate the new delay assuming it directly scales with capacitance. Discuss implications on circuit timing.

💡 Hint: Consider the relationship between capacitance and delay according to formulae from your studies.

Challenge 2 Hard

During LVS verification, you find a mismatch involving a missing power supply connection. How would you identify and correct this issue in your layout?

💡 Hint: Look for visual indicators or verify through simulation to catch connectivity errors.
