Abstract

A method and system is presented for optimizing the number of required measurements to obtain in real-time by an automated tester that tests a device under test. During a test run, historical measurements are obtained and tracked. Each subsequent iteration the test attempts to re-measure the fewest number of measurements in real-time to obtain an accurate reflection of whether the device being tested passes or fails based on the real-time measurements and substituting historical measurements for those required measurements that were not taken in real-time.
