The DECA has implemented a power monitor chip to monitor the FPGA core power voltage and
current.
Figure 3-16
shows the connection between the power monitor chip and the MAX 10 FPGA.
The power monitor chip monitors both shunt voltage drops and FPGA core power voltage.
Programmable calibration value, conversion times, and averaging, combined with an internal
multiplier, enable direct readouts of current in amperes and power in watts.
Table 3-7
shows the pin
assignment of power monitor I2C bus.
