ABSTRACT:
Method for monitoring a real time clock and a device having real time clock monitoring capabilities, the device includes: (i) a real time clock tree, (ii) a clock frequency monitor that is adapted to determine a frequency of a real time clock signal, during a short monitoring period; (iii) a monitoring enable module, adapted to activate the clock frequency monitor during short motoring periods and to deactivate the clock frequency monitor during other periods, wherein the monitoring enable module is adapted to determine a timing of the short monitoring periods in a non-deterministic manner; and (iv) a real time clock violation indication generator adapted to indicate that a real time clock violation occurred, in response to an error signal provided from the clock frequency monitor.
