Power Monitoring with XADC on AC701
to switch all 18 measurements into the XADC.
Table 2-2
details the power rails monitored
on the AC701.
The current sense values of V
CCINT
, V
CCAUX
, V
CCBRAM
, 1.5V supply, and V
CCO_ADJ
along
with voltage levels of 1.5V supply, V
CCO_ADJ
, and 1.8V supply are available on the AC701
board's onboard MUX positioned at U13. The differential output of the MUX is connected
to auxiliary pin 1 (V
AUX
P/N 1) of XADC and each channel is sampled once per second by
the MicroBlaze™ processor program running as part of the AC701 AMS Targeted
Reference Design.
The current sense values of 1.8V supply, 3.3V supply, MGTAVCC, and MGTAVTT along
with voltage levels of 3.3V supply, MGTAVCC, and MGTAVTT are available on the AC701
board's onboard MUX positioned at U14. The differential output of the MUX is connected
to auxiliary pin 9 (V
AUX
P/N 9) of XADC.
