The invention is a truth table-based failure isolation matrix in an Automated Test Equipment (ATE) environment to enable the mapping of measured results and/or test outcomes to probable causes of failure (PCOF). The failure isolation matrix is hierarchical in that it applies to both individual tests as well as groups of tests. For each level in the hierarchy, columns represent individual outcomes verified against expected results to produce a resultant outcome and rows represent possible combinations of measurement outcomes or outcome vectors. For groups of tests, the measurement results represent the combined results of the individual tests within the test group. The resultant matrix is a pattern of vectors that can be pattern matched against prior history of result patterns to further improve the accuracy and narrow the scope of PCOF.

System for enhancing ATE fault isolation capability using a truth table based on a failure isolation matrix

A drag-and-drop workflow editor in an Automated Test Equipment (ATE) environment to create coherent time domain aligned test programs. This includes graphical interface channel diagrams with channel headers, channel timelines, designer items defining test operations, measurement references and trigger references to define temporal relationships in a time domain environment.

System for providing ATE test programming by utilizing drag-and-drop workflow editing in a time domain environment

The system includes an ATE which produces a plurality of test signals and test results for electronic devices by a test instrument or instruments therein. An execution engine responsive to the test results runs multiple test operations from the test instruments within a coherent time domain and maintains a temporal relationship between the multiple test results. The multiple test signals and test results are then displayed in a time coherent alignment.

System and method for providing temporal visualization of signal relationships in a coherent time-domain ATE test execution environment

The system includes an integrated sequenced arrangement of parametric type instruments, automated guided prober test instruments, and a test instrument system using analog signature analysis for identifying faults in circuit card assemblies, under control of a software system with a mass interconnect system.

System and computer program product for performing comprehensive functional and diagnostic circuit card assembly (CCA) testing

A system and method for testing electronic circuit devices. The system has a central processing unit with a plurality of separate core processing units. The utility service program is initiated at the startup of the computer program which acts as an intermediary between user applications and the computer operating system. The utility service is responsive to an ATE execution engine to set an affinity for one or more processing cores for exclusive use for the ATE execution engine. The ATE execution engine communicates with the utility service to reserve one or more processing cores for execution of the program for testing electronic devices.
