Abstract:
In a method and system for testing a test sample (), a simulation program () is used to augment test results provided by a legacy test system (). The legacy test system () includes a measuring device () providing a test input () to the test sample () and receiving a test output () from the test sample () in response to the test input (). The simulation program () simulates the test sample () by predicting a simulated output () of the test sample () in response to receiving a simulated input (). A plurality of simulated failures is simulated in the simulation program (), with each simulated failure generating a corresponding simulated output. The simulation program () includes a model () for the measuring device (), the model () providing the simulated input (). A comparator () compares the test output () with the simulated output () to determine a match. The simulated failure providing the match is used to predict a predicted failure location within the test sample ().
