4.11.3. Current Measurement

To demonstrate low power feature, Cyclone® 10 LP FPGA power rails are isolated with resistors for voltage drop measurement either manually or automatically.

VCCINT, VCCA, and VCCIO_3.3V support automatic current measurement. The voltage drop across sense resistors are connected to MAX® 10 integrated ADC with current sense amplifiers. Refer to the figure below.

The selected MAX® 10 10M08SA-U169 contains one ADC with 9 analog input channels. Three channels are used for Cyclone® 10 LP FPGA current measurement and six channels are used for Arduino analog.

Other Cyclone® 10 LP FPGA power rails support manual measurement by measure voltage drop across sensing resistors with a multi-meter.
