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.

The invention claimed is: 1. A method for generating a rule-based file for producing integrated circuit, comprising: obtaining a rule document associating design rules and design rule values; generating a table file from the rule document associating design rule names for the design rules with corresponding ones of the design rule values, wherein the step of generating a table file comprises: converting the first design rule document into a text file; checking for a rule indicator in the text file; and replacing information adjacent to the rule indicator with a design rule value for a design rule found with the rule indicator; obtaining a parameterized rule file having logical operations associated with the design rule names; and replacing the design rule names in the parameterized rule file with corresponding ones of the design rule values in the table file. 2. The method of claim 1 wherein the parameterized rule file is selected from a design rule document, a layout versus schematic document, an extraction technology document, and a technology file. 3. The method of claim 1 wherein the rule document is the first design rule document, and wherein the parameterized rule file is a parameterized design rule check file. 4. The method of claim 1 wherein the step of replacing the design rule names comprises: comparing the design rule names in the parameterized design rule check file with corresponding design rule names in the table file to obtain the design rule values; and generating a design rule check file having the logical operations associated with the design rule values. 5. The method of claim 4 wherein the step of replacing information comprises selecting the information from a first type of information. 6. The method of claim 5 further comprising: storing the design rule check file; checking for a second type of information; and repeating the step of replacing the design rule names using the second type of information to provide another design rule check file. 7. The method of claim 5 further comprising: checking for a second design rule document; repeating the step of generating a table file using the second design rule document to provide another design rule check file. 8. The method of claim 7 wherein the second design rule document is for scaling to accommodate lithography. 9. A signal-bearing medium containing a program for producing integrated circuit which, when executed by a processor causes execution of a method comprising: obtaining a first rule document associating design rules and design rule value; generating a table file from the first rule document associating design rule names for the design rules with corresponding ones of the design rule values, wherein the step of generating a table file comprises: converting the first design rule document into a text file; checking for a rule indicator in the text file; and replacing information adjacent to the rule indicator with a rule value; obtaining a parameterized rule file having logical operations associated with the design rule names; and replacing the design rule names in the parameterized rule file with corresponding ones of the design rule values in the table file. 10. The method of claim 9 wherein the step of replacing the design rule names comprises: comparing the design rule names in the parameterized rule file with corresponding design rule names in the table file to obtain the design rule values; and generating a design rule check file having the logical operations associated with the design rule values. 11. The method of claim 10 wherein the step of replacing information comprises selecting the information from a first type of information. 12. The method of claim 11 further comprising: storing the first rule file; checking for a second type of information; and repeating the step of replacing the design rule names using the second type of information to provide a second rule file. 13.
