You may observe a high current value displayed at the power utility in the Board Test System, which is different from the value measured when connecting directly with the power register.
The core current of the development kit may supplied from several power register devices, and there is an equation to get the right value and display it on the Board Test System.
For example, for the Intel® Stratix® 10 GX FPGA Development Kit, the core current is provided by 3 devices, one unit of LTM4677 and two units of LTM4650, and we could only read the Iout from LTM4677, so we need to get the result with an equation. The Board Test System uses Linear_5s_11s format to read the output current from LTM4677, and it is not the actual Ivcc, so we will need to use the equation to obtain the result and display it on the GUI.
