Abstract
A digital electronic circuit includes: a plurality of sequential elements; at least one data-conducting path connecting an input sequential element to a destination sequential element; a clock outputting a clock signal on a clock tree for setting the speed of the sequential elements; a monitoring device receiving, as an input, at least one data signal traveling on a conducting path and arriving at a destination sequential element, the monitoring device including: a module for defining at least one detection window according to the clock tree; and a detector for detecting a transition of each data signal received during a detection window; and wherein each detection window is defined so as to enable the detection or anticipation of a fault corresponding to a violation of the rise time or the maintenance time of a data signal relative to a clock signal edge received by the destination sequential element receiving the data signal.
