Abstract

Voltage distortion (noise) and delay violations(skew) contribute to the signal integrity loss and ultimatelyfunctional error, performance degradation andreliability problems. We present a BIST-based testmethodology that includes two special cells to detectand measure noise and skew occurring on the interconnectsof the gigahertz system-on-chips.
