Abstract
A system and method for automatically creating testcases for design rule checking comprises first creating a table with a design rule number, a description, and the values from a design rule manual. Next, any design specific options are derived that affect the flow of the design rule checking, including back end of the line stack options. Then, the design rule values and any design specific options (including back end of the line stack options) are extracted into testcases. Next, the testcases are organized such that there is one library with a plurality of root cells, further comprising one root cell for checking all rules pertaining to the front end of the line, and another root cell for checking design specific options including back end of the line stack options. Finally, the DRC runset is run against the testcases to determine if the DRC runset provides for design rule checking.
