Abstract
Method for diagnosing faults in a system under test (SUT) are provided. A representative method includes identifying at least some portions of the data transmission paths of the SUT capable of introducing errors in data transfer; providing constraints defining relationships of at least some of the portions of the data transmission paths; and diagnosing the SUT with respect to the constraints. Systems, computer-readable media and other methods also are provided.
Claims32
A method for diagnosing faults in a system under test (SUT), the SUT defining data transmission paths through which data are transferred, said method comprising:
- identifying at least some portions of the data transmission paths of the SUT capable of introducing errors in data transfer;
- providing constraints defining relationships of at least some of the portions of the data transmission paths identified;
- and
- diagnosing the SUT with respect to the constraints.
A method for diagnosing faults in a system under test (SUT), said method comprising:
- providing a dataflow model representative of the SUT, the dataflow model including information corresponding to a relationship of error detection capabilities of the SUT;
- and
- diagnosing the SUT with respect to the dataflow model.
A system for diagnosing faults in a system under test (SUT), said system comprising:
- a dataflow model representative of error detection capabilities of the SUT;
- and
- a reasoning engine associated with said dataflow model, said reasoning engine being adapted to evaluate test results corresponding to the SUT in relation to said dataflow model.
A system for diagnosing faults in a system under test (SUT), said system comprising:
- means for receiving test results corresponding at least some portions of data transmission paths of the SUT;
- and
- means for diagnosing the SUT with respect to constraints defining relationships of at least some of the portions of data transmission paths of the SUT.
A diagnosis system stored on a computer-readable medium, the diagnosis system being adapted to diagnose faults in a system under test (SUT), said diagnosis system comprising:
- logic configured to identify at least some portions of the data transmission paths of the SUT capable of introducing errors in data transfer;
- logic configured to provide constraints defining relationships of at least some of the portions of the data transmission paths;
- and
- logic configured to diagnose the SUT with respect to the constraints.
