Abstract
Method and apparatus are described for providing a rule file. More particularly, a design rule document is converted to a table file of design rules and associated design rule values, where design rules follow a naming convention to maintain uniqueness among them. A parameterized design rule check (PDRC) file is obtained. Such a PDRC file calls out design rule names instead of design rule values. A computer program is used to exchange design rule values associated with design rule names in the table file for the design rule names called out in the PDRC file to provide a design rule check (DRC) file. This method and apparatus also apply to any technology file containing parameterized rules.
