Abstract
An integrated circuit includes delay monitors that monitor the delays of data signals from the digital circuitry by generating pulses having widths determined by the delays. In some embodiments, the delay monitor is implemented as a digital circuit that includes a pulse generator and an event generator. The delay monitor receives a data signal and a clock signal used to clock the data signal. The pulse generator generates pulses from the received data and clock signals, where the widths of the pulses are determined by a delay of the data signal relative to the clock signal. The event generator generates events that are distributed in time relative to the clock signal. As a result, the delay is estimable based on an overlap between the events and the pulses.
