AMS Bring-up with the AMS101 Evaluation Card
Power Monitoring
In addition to measuring the analog signals from the AMS101 evaluation card, the AC701
also uses the XADC as a system monitoring solution for measuring the voltage, load
current and calculated power for nine of the AC701 board analog power supplies. By
offering 12-bits, 1 MSPS and up to 17 externally multiplexed inputs, the XADC is a good
solution for monitoring voltage and current on all Artix-7 FPGA applications. Figure 13
shows an example of the AC701 monitoring V

, V

and the 1.5V
supply.
In conjunction with the AMS Evaluator, the AC701 AMS reference design also measures
the voltages, current and power for V
CCO_ADJ
, the 1.8V supply, the 3.3V supply,
MGTAVCC and MGTAVTT.
