  • Patent number: 8222910
    Abstract: The innovation relates to systems and/or methodologies for error detection during sub-assembly in high voltage analog circuits. A signal driver communicates test signals to one or more high voltage analog circuits, and a state machine compares the electrical and/or thermal responses of the high voltage analog circuits to a set of predetermined expected results (e.g., signatures). The signal driver and state machine can be incorporated into the high voltage analog circuits. The expected results can be stored in the target circuits in the form of look-up tables, matrices, and so forth. Errors, such as, dry solders and bridge solders can be determined based on the comparison of the obtained responses to the expected signatures.
