Abstract
A method and apparatus for data analysis according to various aspects of the present invention is configured to automatically identify a characteristic of a fabrication process for components based on test data for the components.
Claims38
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 and automatically analyze the test data to identify a characteristic of the fabrication process for the components, wherein the diagnostic system comprises a pattern recognition system configured to recognize a pattern in the test data, wherein the pattern recognition system includes a feature extractor configured to extract a feature from the test data associated with the pattern, wherein the feature extractor calculates at least one of a mass, a centroid, a geometric moment, and a moment of Hu based on the test data.
A test data analysis system for analyzing test data for a set of components fabricated and tested using a fabrication process, comprising:
- a memory for storing the test data;
- and
- a diagnostic system having access to the memory and configured to identify a characteristic of the fabrication process based on the test data, wherein the diagnostic system comprises a pattern recognition system configured to recognize a pattern in the test data, wherein the pattern recognition system includes a feature extractor configured to extract a feature from the test data associated with the pattern, wherein the feature extractor calculates at least one of a mass, a centroid, a geometric moment, and a moment of Hu based on the test data.
A computer-implemented method for testing components fabricated and tested according to a fabrication process, comprising:
- obtaining test data for the components;
- automatically identifying a characteristic of the fabrication process based on the test data, wherein automatically identifying the characteristic comprises recognizing a pattern in the test data, wherein antomaticatly identifying the characteristic comprises extracting a feature from the test data associated with the recognized pattern, wherein the feature comprises at least one of a mass, a centroid, a geometric moment, and a moment of Hu based on the test data;
- and
- storing information relating to the identified characteristic in a memory.
A medium storing instructions executable by a machine, wherein the instructions cause the machine to execute a method for analyzing test data comprising:
- obtaining test data for the components;
- automatically identifying a characteristic of the fabrication process based on the test data, wherein automatically identifying the characteristic comprises recognizing a pattern in the test data, wherein automatically identifying the characteristic comprises extracting a feature from the test data associated with the recognized pattern, wherein the feature comprises at least one of a mass, a centroid, a geometric moment, and a moment of Hu based on the test data;
- and
- storing information relating to the identified characteristic in a memory.
