A.2. System Management

Two Intel® MAX® 10 FPGAs (10M16SCU324C8G) are used for system management. System Intel® MAX® 10 acts as system controller. It handles FPGA AvST configuration, I2C bus access, fan speed control and system reset functions. The UB2/PWR Intel® MAX® 10 acts as Power manager and on-board JTAG controller. Refer to below description for each function:

  • Power management: Control systems and FPGA power up and optional down sequence, supervise power regulators/switches status and manage power faults, supervise temperature sensor interrupt signals and manage temperature faults.
  • JTAG controller: Manage JTAG chain topology, JTAG master source and JTAG slaves by S19.
