3.2. SmartVID Error Message Bits

The SmartVID error message bits store the error message when the Intel Agilex® 7 detects an error in the external voltage regulator.

The SmartVID error message contains information about the type of error and the specific error details. You can retrieve the contents of the error message from the generic_sdm_data_out signal of the Advanced SEU Detection Intel® FPGA IP.

11:0 Specific SmartVID error details:
  • 12'd0—no error
  • 12'd1—NACK on PMBus address
  • 12'd2—NACK on PMBus command
  • 12'd3—NACK on PMBus data or payload
  • 12'd4—NACK on PMBus general call
  • 12'd5—NACK on PMBus general read

  • 12'd7—NACK on PMBus master abort lost
  • 12'd8—FPGA user abort error
  • 12'd9—PWRMGT_SDA signal stuck low
  • Remaining values—reserved
Note: When a SmartVID error occurs, Intel® recommends that you check the integrity of the SmartVID signals and the voltage regulator on board.
