Title (EN) ON-CHIP FREQUENCY MONITORING
(FR) SURVEILLANCE DE FRÉQUENCE SUR PUCE
Abstract:
(EN) In certain aspects of the disclosure, a frequency monitor includes a counter configured to receive a monitored clock signal, to count a number of periods of the monitored clock signal over a predetermined time duration, and to output a count value corresponding to the number of periods of the monitored clock signal. The frequency monitor also includes a comparator configured to receive the count value from the counter, to receive an expected count value, to compare the count value from the counter with the expected count value, and to output a pass status signal or a fail status signal based on the comparison.
(FR) Certains aspects de l'invention concernent un dispositif de surveillance de fréquence comprenant un compteur conçu pour recevoir un signal d'horloge surveillé, compter un nombre de périodes du signal d'horloge surveillé pendant une durée prédéterminée, et émettre en sortie une valeur de comptage correspondant au nombre de périodes du signal d'horloge surveillé. Le dispositif de surveillance de fréquence comprend également un comparateur conçu pour recevoir la valeur de comptage provenant du compteur, recevoir une valeur de comptage attendue, comparer la valeur de comptage du compteur à la valeur de comptage attendue, et émettre en sortie un signal d'état de réussite ou un signal d'état d'échec en fonction de la comparaison.
