System fidelity factor in analysis of inverter-interconnect-inverter VLSI systems

摘要

The paper presents the method to classify of the shape of the clock signal distortions and rough estimation of a clock skew by means of system fidelity factor (SFF). The method is based on cross-correlation coefficient calculations for periodic clock signal. The signals are represented by their Fourier series. The steady state in clock distribution networks is assumed. In the paper is presented the formula for SFF coefficient and an example of its calculation.
