1.3.5. Correlation

The following results show the correlation between the PDN tool and the post-layout system PDN impedance profile (lower right figure) for one of Intel's development kit boards. In the post-layout analysis, the simple VRM model from the PDN tool was used. Since the PDN tool is already considering PKG and die parasitics, both results are well correlated.

Note: The PDN tool does not display the on-die capacitance in the result graph. Die capacitance is utilized for determining FEFFECTIVE.
