Abstract

A method correlates a timing target for electronic design automation (EDA) design tools by comparing slack distributions. A method of designing an integrated circuit can include designing an integrated circuit by RTL synthesis with embedded timing analysis and optimization and placement of cells with embedded timing analysis and optimization. The method can also include designing an integrated circuit by routing with embedded timing analysis and optimization; performing reference timing analysis; performing reference timing analysis and embedded timing analysis using a parasitic estimation model. The method can also include comparing at least two slack distributions resulting from timing analyses. The method can include calculating and comparing autocorrelation functions of slack distributions. The method can include calculating interrcorrelation functions of slack distributions. An embodiment teaches an integrated circuit designed by the method taught. Another embodiment teaches a computer program product according to the method taught.
