VID setting is incorrect for Stratix 10. I am using MP2975GU as the voltage regulator.

Hello, 

Check items below:

1- PMBus - please ensure PWRMGT_SCL PWRMGT_SDA are pullup properly to 1.8V. If you use PMBus target/slave mode, please connect PWRMGT_ALERT as well. 

2- Please check if your MPS GUI is listing 8-bit value, Quartus wants 7-bit. 

3- Slave type = "Others" only for if the regulator is fully PMBus-compatible with standard commands and voltage formats. If your regulator is not in the intel GUI list and requires vendor-specific sequences, smartVID may fail. 

4- If you dont want to use smartvid, it is recommended to use correct part number with device without smarVID feature. 

5- If you plan to re-design your board, it is recommended to use the validated power regulator such as LTM4677.

Hello, 

Do you have further question?

Thank you for your advice. I 've switch to another project so this problem is delayed .Now i coming back with this problem.  With your suggestion, I 've checked and this is my response for each : 

1. Pull up voltage for PWRMGT_SDA and PWRMGT_SCL is correctly connect to 1V8 pullup voltage. a Shifter is connect between 3V3 Voltage and that 1V8 Voltage. PWRMGT_ALERT is also assigned like your suggestion.

2. The Address range of MPS GUI is set up with 01H to 7FH and the return address is 7C. So i think the address of the MPS GUI is 7bit .

3. The Voltage Regulator is MP2975 and with the FPGA SmartVID device suggestion, my Voltage reguator is API Validated with only Agilex 7 Family. So i think this is the problem. 

4. My Stratix 10 with suffix -VG so we cant turn off the VID Mode.

5. My hardware board is done, so redesign is too expensive for us.

Here is my response from your advice. I truely appreciate to you . 

My team realized that might be the Altera USB Blaster is wrong type. We ordered another one and will test with the new one. As soon as this work complete , i will announce you. Again , thank you so much
