Technology file process rule validation

A system for validating technology file design rules, the system comprising:

• a processor;
• and
• a memory device containing instructions, which when executed by the processor, cause the processor to:
• obtain a technology file including a plurality of design rules that are to be validated;
• obtain an input test library from an internal storage or a remote storage of the system, wherein the input test library includes a plurality of design rule cell-views corresponding to the plurality of design rules, wherein each design rule cell-view includes a first set of failed test cases associated with a corresponding one of the plurality of design rules;
• test, using a Design Rule Driven (DRD) tool with specification requirements of the DRD tool, the plurality of design rules based on the plurality of design rule cell-views to obtain test output data, wherein the test output data includes, for each of the plurality of design rules, a second set of failed test cases associated with the corresponding one of the plurality of design rules;
• determine a validation result 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 corresponding one of the plurality of design rules, the validation result being indicative of efficacy of the corresponding one of the plurality of design rules;
• and
• generate a validation report including the validation result for each of the plurality of design rules.

A method of validating technology file design rules, the method comprising:

• obtaining a technology file including a plurality of design rules that are to be validated;
• obtaining an input test library including a plurality of design rule cell-views corresponding to the plurality of design rules, wherein each design rule cell-view includes a first set of failed test cases associated with a corresponding one of the plurality of design rules;
• testing, using a Design Rule Driven (DRD) tool, the plurality of design rules based on the plurality of design rule cell-views to obtain test output data, wherein the test output data includes, for each of the plurality of design rules, a second set of failed test cases associated with the corresponding one of the plurality of design rules;
• determining a validation result 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 corresponding one of the plurality of design rules, the validation result being indicative of efficacy of the corresponding one of the plurality of design rules;
• and
• generating a validation report including the validation result for each of the plurality of design rules,
• wherein the first set of failed test cases include a layout of a circuit design which is not as per constraints defined by the corresponding one of the plurality of design rules,
• wherein each of the plurality of design rule cell-views includes a plurality of test cases,
• wherein each test case of the plurality of test cases is one of pass test case and fail test case, and
• wherein the method further comprises:
• for each of the plurality of design rule cell-views;
• performing a check on whether the plurality of test cases is compliant with one or more DRD tool requirements;
• and
• modifying at least one test case that is determined to be non-compliant to the one or more DRD tool requirements.
