3.7 System Monitor
All power rails are sequenced and monitored by a system monitor IC. The device used in this design is a TI
Fusion UCD90120A. The TI Fusion controller monitors certain voltage readings, current readings, and Power OK
signals to determine the state of the system. D6 and D7 can be decoded to understand the system state (see
Section LEDs
for LED Location).

System Monitor Warning Reasons
•
FPGA Core Temperature near maximum (95 degC): Warning logged
•
Voltage rail outside recommended values in Kintex Ultrascale Datasheet (DS892): Warning logged
System Monitor Faults and Responses
•
FPGA Core Temperature above operating above maximum (105 degC): Reconfigure FPGA from failsafe
region.
•
Voltage rail outside maximums specified Kintex Ultrascale Datasheet (DS892): Power down board.
A PC can directly interact with the TI Fusion IC via the PMBUS header in the design. This requires the following
items:
