Power Measurement

Ten power supply rails have on-board voltage and current-sense capabilities. These

devices and rails are split from the primary supply plane by a low-value sense resistor

for the A/D converter to measure voltage and current.

Table 2–59 shows the targeted rails where Measured Net Name column shows the name

of the rail being measured, and the devices attached to that are listed under

Power Pin Name and Description columns. If no subnet is named, then the power is the

total output power for that voltage.
