A design rule checker (DRC) is a tool which ensures that the layout of the circuit adheres to a set of design rules. These rules specify the minimum and maximum dimensions for various elements of the circuit, such as the width of a path or the distance between two vias. The DRC will automatically check the layout against these rules and flag any violations. It enables the designer to make corrections before the circuit is manufactured. This helps to prevent errors that could cause the circuit to malfunction or fail. Learn the concepts of the Design Rule Checkes and how to use them with the LayoutEditor.
