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.

Best Regards,
