The system controller reads and displays SYSMON based measurements prior to
configuring the UltraScale FPGA. Bank 66 of the Kintex UltraScale device is the default
SYSMON bank and is ready to monitor the SYSMON auxiliary channels at power-up.
Auxiliary channels VAUX0, VAUX2, and VAUX8 are used to monitor MGTVCC, the ADG707
analog MUX, and MGTAVTT, respectively. At power-up, jumpers J80 and J81 connect
SYSMON's VP and VN pins to ground, setting the default SYSMON I2C address to 0x32. This
power-up default I2C address is used by the system controller to access SYSMON data.
If the KCU105 system controller SYSMON menu is used after the UltraScale FPGA has been
configured with a design, the UltraScale resident design must contain logic to enable I2C
access to the UltraScale system monitor and the internal (VCCINT, VCCBRAM, VCCAUX) and
auxiliary channels (VAUX0, VAUX2, VAUX8). Designs that access I2C devices through the
TCA9548 I2C switch must also deassert the TCA9548 reset pin from logic within the
UltraScale FPGA. There is an external pull-up on this reset signal. See UltraScale Architecture
System Monitor User Guide (UG580)
Through the SYSMON menu, single readings or a continuous scan of the voltages, currents,
power, and temperature are available. The minimum and maximum current usage for the
monitored rails are also displayed and are reset each time the SYSMON menu is entered.
