Power Sense Lines

Sense lines from the die power rail to the ball accurately account for the voltage drop in the package at high currents. The power supply uses the sense lines as the feedback reference to avoid having the wrong voltage level under load. You must use the power sense lines in this fashion when using the SmartVID features.

The power sense lines are dedicated pins on the FPGA. Refer to the Intel® Arria® 10 GX, GT, and SX Device Family Pin Connection Guidelines for details.
