Abstract
In some embodiments, a chip includes clock generation circuitry to create a clock signal, and reference signal oscillator circuitry to produce a reference signal with a higher frequency than the clock signal. The chip includes a counter to change a count value in response to changes in the reference signal; and count logic circuitry to cause count storage circuitry to read the count value in response to at least some changes in the clock signal and to make at least some of the values in the count storage circuitry related to a duty cycle of the clock signal available to an external tester. Other embodiments are described and claimed.
