Virtex-6 System Monitor - What happens if AVSS of System monitor is not connected to GND?


All of the System Monitor pins should be connected to GND in order todisable it.

Can the user deviate from the recommendations?What happens if AVSS of System monitor is connected to 2.5V?


Connecting AVSS or VREFN to anything other than GND is completely unsupported. If it is connected to any power supply, there is the possibility of damage occurring.

As this is not a supported setup, it has not been tested. Therefore, Xilinx cannot guarantee what the outcome will be, but there is the possibility of damage occurring outside of the System Monitor.

Xilinx cannot support any designs that do not have AVSS_SM and VREFN connected to GND.
