Why does the Intel® PDN Tool suggest 0 bulk decoupling capacitors with low current power supply rails? - Why does the Intel® PDN Tool suggest 0 bulk decoupling capacitors with low current power supply rails? Description The Intel Power Distribution Network (PDN) Tool might suggest 0 bulk decoupling capacitors with low current power supply rails. Low current power supply rails will have a higher target impedance than high current power supply rails. A low current power supply may not need bulk decoupling capacitors to meet the target impedance because the Voltage Regulator Module (VRM) may already have a low enough output impedance. Resolution The PDN Tool is correct but Intel do not recommend omitting bulk decoupling capacitors from your PCB design. To decouple your Intel® FPGA design, you should use best-practice decoupling techniques and consider adding bulk capacitance.
