Abstract:
A bus based system comprising a first unit, a second unit, and a link between the first and second units, the first and second units being respectively coupled to the link at first and second different locations, the second unit having an address, the first unit being arranged for generating a data pattern associated with the address of the second unit and for coupling the data pattern to the link, bits of said data pattern having a defined relationship with the address of the second unit, the second unit being arranged to be responsive to data patterns transmitted via the link for (a) comparing said data pattern with a data pattern generated by the second unit and for deriving a test result, and (b) signaling that the data pattern was successfully transmitted from the first unit to the second unit via the link in response to the defined relationship existing between the address of the second unit and bits of a data pattern coupled to the second unit via the link being the data pattern associated with the address of the second unit.
