1. A computer-implemented method for providing design rule checking in an electronic design automation (EDA) application, comprising:

  • obtaining, through a graphical user interface (GUI), a set of design rules and, for each design rule in the set of design rules, a dynamic rule setting that indicates whether or not the design rule is a dynamic design rule;

    obtaining a dynamic rule preference that indicates whether or not dynamic rule checking is to be performed; and

    in response to a computer determining that the dynamic rule preference indicates that dynamic rule checking is to be performed and that a schematic was switched from a read-only mode to a read/write mode, the computer automatically applying each design rule whose dynamic rule setting indicates that the design rule is a dynamic design rule to the schematic by;

    destroying non-signed-off markers in the schematic;

    creating new markers based on applying each design rule whose dynamic rule setting indicates that the design rule is a dynamic design rule;

    adding only those new markers to the schematic that do not match an existing signed-off marker.
