Abstract
An electronic circuit includes a clock signal generator configured to deliver a clock signal. A propagation circuit is configured to propagate the clock signal on a plurality of propagation branches. A number of timers are coupled to at least some of the branches. The timers are clocked by corresponding replicas of the clock signal and configured to generate a pulse signal every N pulses of the corresponding replica of the clock signal. A comparator is configured to generate an alarm signal having a first state when two of the pulse signals are phase-offset with respect to one another.
