Abstract
A method and an apparatus for checking a signal line are provided. The method includes: obtaining custom design information of a target signal line in a circuit schematic, and generating a layout design rule corresponding to the target signal line based on the custom design information; checking whether the target signal line meets the layout design rule in a circuit layout corresponding to the circuit schematic; and adding a first label to a position of the target signal line in the circuit layout when the target signal line in the circuit layout does not meet the layout design rule. The first label is configured to indicate that the target signal line does not meet the layout design rule.
