Hi , 

Does 1SG085HN2F43E2LG must need to connect the PMBUS? >> Yes as per the recommendation,

Kindly find the explanation.

 Intel Stratix 10 devices will not configure or function correctly if the core voltage is driven by a non-PMBus compliant regulator with a fixed output voltage

Hi

我看了下这个文档,应该是-v的才必须接PMBUS,-L的应该可以不接对吧?批注 2020-03-11 212214.png

Hi Rxie ,

Kindly find the my reply below in details.

For Stratix 10 with support for SmartVID standard power ,you must connect the PWRMGT_SCT and PWRMGT_SDA connect to power management bus.

 

There are other opn in which the power line is fixed, that is L and X , in that there is no support for Smart VID , the power is fixed ,

 

Kindly find the reference in PCG : PAGE NO:28

If the OPN have L or x no support for SMART VID , so connection is not required , hope it clarifies
