1.2.2.1.3. Meeting Target Impedance when Entering 0 A into the PDN Tool
If you enter 0 A into some low current power supply pin types, such as VCCBAT, the PDN tool calculates a high effective impedance. Other power supply pin types may also show this problem.
The minimum allowable non-zero current entry into the Intel PDN Tool is 0.001 A. If you enter 0 A for currents below 0.001 A, a divide-by-zero or multiply-by-zero problem can occur.
To avoid this problem, enter 0.001 A to calculate decoupling for currents less than 0.001 A. Entering 0.001 A does not significantly burden the decoupling solution.
