Explanation:

• Design Rule Checking (DRC) checks for various design rules within the active layout (the active Layout View window). In hierarchical designs, all levels of the hierarchy are checked when the DRC is run from the top level.
• When you run DRC on a layout you can perform several types of checks:
• Cell-based checking, which allows rules to be programmed into parameterized layout cells.
• Rat lines checking, which checks for any rat lines (layout connection lines) in the layout, indicating a layout not properly put together.
• Polygon-based checking, which applies a set of rules to the polygons that are generated from a flat version of the layout .
