US Patent 7600169 Systems and methods of test case generation with feedback

Systems and methods for implementing test case generation with feedback are disclosed. An exemplary system for test case generation with feedback comprises a plurality of knobs identifying test values for a device under test. A plurality of buckets is each associated with at least one of the test values, each bucket having a weight value for the associated test value. A failure analysis module is operatively associated with the device under test, the failure analysis module changing at least some weight values based on feedback from test operations for the device under test. A test case generator selects test values for test operations based on the weight value for the associated test value.
