Signal state durations, such as the pulse-width, of on-chip signals are often critical to the successful operation of an integrated circuit. The signal state durations measured by on-chip technology provide signal state duration information to an on-chip signal state duration control system. The signal state duration control system uses the information to adjust the signal state duration of an on-chip signal. In one embodiment, the signal state duration of the on-chip signal is the pulse width of the on-chip signal. The signal duration measurement and adjustment system is, for example, useful for measuring the state duration of signals such as self-resetting signals, which are difficult to externally measure and adjust signal state durations using on-chip technology.
