Abstract (en)

[origin: WO8100475A1] An automatic test apparatus (10) coupled to a bi-directional internal data and control bus (26) of a programmed microprocessor@based system (14) tests the performance of the system (14) in real time. Signal responses of the bus (26) within a known good system (12) are compared in real time to signal responses on the bus (26) of the unknown system under test (14) in order to identify faults. Faults are isolated by a sequential algorithm which stops operation at the designated occurence of a fault, typically the first fault, and thereupon traces the error causing the fault to the subsystem or components in the system under test (14) supplying the indicated error signal to the bi-directional bus (26).
