1. A test system, comprising:
- a tester configured to test a set of components and generate test data for the set of components, wherein the components are fabricated in accordance with a fabrication process; and
a diagnostic system configured to receive the test data from the tester, automatically analyze the test data, and identify a characteristic of the fabrication process for the components according to the analysis, wherein the diagnostic system comprises a pattern recognition system configured to;
recognize a pattern in the test data;
compare the recognized pattern to a known pattern associated with the characteristic; and
automatically learn an additional pattern associated with a new characteristic based on the recognized pattern, wherein automatically learn the additional pattern associated with the new characteristic does not require the pattern recognition system to retrain.
