What are lambda based design rules? What is nm in 10nm technology node? Do you know about under bum density? Any prior experience of PnR? How do you import design in PnR? Why ID layers have been given in lower nodes (10nm)? Why nwell continuity is required? Have you done scripting? Can you write an algorithm? What is drive strength? Why the industry is moving towards lower technology nodes like 7nm or 5nm? What are challenges seen in lower technology node? What are the difference between 45nm and 65nm routing rules? any new rule in the 45nm? Why foundry define DRM, routing rules? What is stack means? How many types of metal layers are in 65nm/45nm? Why metals are of different thickness? Why thin metal are in lower position and thick metals are at upper position in a defined Stack? What is the need of several types of metal layer in a design? What do you mean by RDL layer? Why it requires? How many types of routing? What is the sequence of that? Power is routed first or clock is routed
