PDN Decoupling Methodology Review
The PDN tool 2.0 provides two parameters for guiding PCB decoupling design: Z

.
PDN Circuit Topology
The PDN tool 2.0 is based on a lumped equivalent model representation of the power delivery network
topology.

Notes:
1. You can define or change VRM parameters in the Library sheet of the PDN tool.
2. You can define or change Decoupling CAPs parameters in the Cap Mount, X2Y Mount, and Library sheets of the PDN tool.
3. Rs and Ls are parasitic capacitances and inductances from BGA balls and PCB traces and connections.
4. Represents PCB layers dedicated to power and ground planes.
