Claim 17:
18. An apparatus for monitoring the reliability of an electronic system, comprising:
a communications interface; and
a processing apparatus, operatively coupled to the communications interface, wherein the processing apparatus is configured to
measure, at different measurement times, and according to a predetermined transmission quality measure, a transmission quality of electrical signals transmitted to or from the electronic system over a wired electrical signal transmission path;
compare, for each of the measurement times, the associated measured transmission quality with a respective associated transmission quality reference value previously determined according to the transmission quality measure; and
determine a value of a reliability indicator associated with the respective measurement time in dependence on the result of the associated comparison;
wherein the transmission quality measure comprises a measure of an extent of a subrange of a one- or multi-dimensional operating parameter range of the electronic system in which, according to a predetermined reliability criterion, the electronic system is configured to reliably operate.
