Abstract
In one embodiment, a timing relationship between two signals on an integrated circuit is measured using a ring oscillator on the die of the integrated circuit. The measured time difference is outputted in a digital form. A delay line coupled to the ring oscillator may be used to reduce uncertainty in measurement which may result from the effects of latch circuit metastability. Other embodiments are described and claimed.
