Occasional Contributorstratix 10 PMBUS's issue
Hi,
the full device name tells if you are using a V (SmartVID) or L or X (fixed voltage) type, most likely the former.
Power management guide tells:
Intel Stratix 10 standard power devices (–1V, –2V, –3V power grade) are SmartVID devices. The core voltage supplies (VCC and VCCP) for each SmartVID device must be driven by a PMBus-compliant voltage regulator dedicated to the Intel Stratix 10 –V device that is connected to that Intel Stratix 10 device via PMBus. For Intel Stratix 10 standard power devices, use of a PMBus-compliant voltage regulator for each device is mandatory. 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.

Occasional ContributorHi,i have a issue now,my board have no PMBUS's voltage regulator for fpga,but the PMBUS_SCL and PMBUS_SDA is connected to the the PMBUS of the stm32l071 device. Now,i would like to know if the following two methods are feasible:
1.config device vid mode of operation is PMBUS Master,and the stm32l071 is PMBUS Slave.
2. config device vid mode of operation is PMBUS Slave,and the stm32l071 is PMBUS Master.

Operation of SmartVID supply is explained in detail in power managment guide, particularly its purpose is well explained. Obviously S10 can't achieve full performance without utilizing this feature. If your target is limited test operation with reduced performance, you should be able to fake regulator PMBUS function with STM32. Be aware that S10 may overheat under circumstances.

So is it possible to use all power modules with PMBUS protocol, or is it necessary to use Intel's own power modules？
