Major Tabs of the PDN Tool
Figure 1–2 shows the tabs of the PDN tool spreadsheet. Table 1–2 describes the PDN
tool tabs.
You can input design-specific information in the various tabs to arrive at a very
accurate PDN profile for a given power supply. The following sections describe the
major tabs for the tool.

Tab Description
Release Notes This tab provides the legal disclaimers, the revision history of the tool, and the user agreement.
Introduction
This tab shows the schematic representation of the circuit that is modeled as part of the PDN tool.
The tab also provides related information, such as a quick start instruction, recommended
settings for some power rails and a brief description of decoupling design procedures under
different power supply connection schemes.
Decap Selection
This tab provides an interface to input the various parameters and observe the resultant
impedance profile. This is the main user interface to the tool.
Library
This tab points to various libraries (capacitor, dielectric materials, and so on) that are called by
other tabs. You can change the default values listed as part of these libraries.
BGA Via
This tab provides an interface to calculate the BGA mounting inductance based on design-specific
via parameters and the number of vias.
Plane Cap
This tab provides an interface to calculate the plane capacitance based on design-specific
parameters.
Cap Mount
This tab provides an interface to input design-specific parameters for calculating the capacitor
mounting inductance for two different capacitor orientations (Via on Side [VOS] and Via on End
[VOE]).
X2Y Mount
This tab provides an interface to input design-specific parameters for calculating the capacitor
mounting inductance for X2Y type capacitors.
BOM This tab provides a summary of the final capacitor count needed to meet the target impedance.
