Stratix 10 SmartVID Issue

[hool]

Hi, We have a board with Stratix 10 FPGA with SmartVID. Device programming return errors. We found out that we have SmartVID device and the Power Supply with PMbus conection to S10. But the Power Supply's VOUT_COMMAND and READ_VOUT have different decoding because their LSB is different. VOUT_COMMAND is direct format with LSB = 5mV; READ_VOUT is direct format with LSB = 1mV. Is any chance to run SmartVID device on this board? Your help is really appreciated.

Hi Hool,

Thank you for your patience.

Regarding to your question, if VOUT_COMMAND and READ_VOUT have different decoding, then the Voltage Regulator(VR) cannot be used. The secure device manager(SDM) treat those 2 command with the same decoding.

In order to allow smartVID to work, both VOUT_COMMAND and READ_VOUT must be in same decoding and the VR should meet the requirement in the Intel power management user guide.

You may refer to below link for more information:

Intel® Stratix® 10 Power Management User Guide 

If those VR having different data format for VOUT_COMMAND and READ_VOUT does not meet PMBus protocol.

Hope this answers your question.

Thank you.
