The Altera Power Delivery Network (PDN) Tool User Guide describes how to use the Altera PDN Tool to create and analyze power delivery networks (PDNs).
The Altera Power Delivery Network (PDN) Tool is a Microsoft Excel-based spreadsheet designed to help PCB designers estimate the number, value, and type of decoupling capacitors required for an efficient design. It calculates an impedance profile based on user inputs such as board stackup, transient current information, and ripple specifications. The results serve as a preliminary estimate to determine the optimum number of capacitors to meet a desired impedance target during the early design phase.
