First Claim
Patent Images
1. 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.

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.
