LSI design flow and EDA
Which correctly describes DRC (design rule check) in layout verification?
- AVerifying that the connectivity of the schematic and the layout match
- BVerifying that the layout satisfies manufacturing rules such as minimum width and spacing
- CVerifying the logic function of the RTL by simulation
Show answer and explanation
Answer: B. Verifying that the layout satisfies manufacturing rules such as minimum width and spacing
DRC checks whether layout shapes violate design rules set by the manufacturing process, such as minimum width, spacing and overlap. Confirming that the connectivity of the schematic and layout match is called LVS (Layout Versus Schematic). Both are always performed before mask data is released.
