Difference between the LVS and DRC

Question

What do you mean by LVs and explain why do we do that. Illustrate the difference between the LVS and DRC?

Answer 1

The layout should be drawn according to certain strict design rules. DRC aids in layout of the designs by checking if the layout is abide by such rules.

Subsequent to the completion of layout, we extract the netlist. LVS compares the netlist extracted from layout with the schematic to make sure that the layout is an identical match to the cell schematic.
