Abstract: Embodiments of the present invention relate to an architecture that uses hierarchical statistically multiplexed counters to extend counter life by orders of magnitude. Each level includes statistically multiplexed counters. The statistically multiplexed counters includes P base counters and S subcounters, wherein the S subcounters are dynamically concatenated with the P base counters. When a row overflow in a level occurs, counters in a next level above are used to extend counter life. The hierarchical statistically multiplexed counters can be used with an overflow FIFO to further extend counter life.

Abstract: A clock monitor circuit includes a monitor and a tunable counter. The monitor can monitor a clock under test. The tunable counter can count an integer according to a reference clock and set a target number. If a stable signal relative to the clock under test is toggled, the tunable counter can switch the target number from a large number to a small number. The tunable counter can perform an automatic detection process, so as to transmit a check signal to the monitor. In response to the check signal, if the clock under test is undetectable, the monitor will not transmit any confirmation signal back to the tunable counter, and the tunable counter will gradually increase the integer. When the integer is equal to the target number, the tunable counter generates a failure signal.
