Hello Jenanne,

 

Please follow the below steps to to specify the Power Management and VID parameters and options:

  1. Create an Intel Quartus Prime project using the New Project Wizard available from the File menu.
  2. On the Assignments menu, click Device.
  3. On the Device and Pin Options dialog box, click Configuration.
  4. On the Configuration page, specify the VID Operation mode.
    1. There are two modes available—PMBus Master and PMBus Slave.
  5. On the Device and Pin Options dialog box, click Power Management and VID
  6. to specify the device settings if your device setting is in the PMBus Master mode.
  7. Click OK.
  8. For the power management and VID parameters that can be used with Enpirion Digital regulators
  9. Bus Speed mode : 400KHz/100KHz
    1. Enpirion Regulator support both speeds.
  10. Slave device type : Select EM21XX, EM22XX or ED8401 if they appear on the drop down list.
    1. Please select “Other” for Enpirion,if the above family names doesn't appear.
  11. PMBus device X slave address
    1. Input the PMBus slave address of Enpirion regulator set by customer.
  12. Voltage output format : Auto discovery/Direct format/Linear format
    1. Enpirion only support the Linear format and the N coefficient is -13
  13. When using Auto discovery, please set the direct coefficient m/b/R to 0
    1. When the slave device operates in Linear mode, Auto discovery can be used too
  14. Don't Enable PAGE command
    1. Enpirion doesn't support Page command
