A method and system disclosed for validating technology file design rules, including obtaining a technology file with design rules that are to be validated. An input test case library is obtained with design rule cell-views for each corresponding design rules. The design rule cell-view includes a first set of failed test cases. An output data is generated by using Design Rule Driven (DRD) tool, to test the design rules based on the design rule cell-views. The test output data provides a second set of failed test cases associated with the corresponding design rule. A validation result is determined for each of the plurality of design rules based on the first set of failed test cases and the second set of failed test cases associated with the design rule. Finally, a validation report is generated including the validation result for each design rules.
