Summary:A circuit for tracking the minimum and maximum duration of an event of interest, and for tracking the minimum and maximum value of a signal of interest, is described. The circuit is connected to a counter for counting a number of clock cycles that the event of interest is active and comprises logic for detecting deactivation of the event of interest and generating a duration end signal; logic responsive to the duration end signal for capturing a value of the counter as a count value in a first circuit configuration, logic for capturing the value of the signal of interest as the count value in a second circuit configuration, logic for comparing the count value with a shadow value; and logic for updating the shadow value based on results of the comparing.
