3.1.1.2. Power Management and VID Parameters

You can use the GUI parameters to configure the Power Management and VID interface if the VID operation is in the PMBus Master mode.

Table 11.  Power Management and VID Parameters
Parameters Value Description
Bus speed mode 16 100 KHz Bus speed mode of PMBus interface when operating in the PMBus Master mode.
400 KHz
Slave device type 16 LTM4677

Supported device types.

Altera recommends you to use one of the slave device type listed in the drop-down menu that has been tested with the Altera FPGA tools. If you are not using one of the slave device type listed in the drop-down menu, select Other option. When you select Other option, refer to the SmartVID Regulator Requirements table, the Supported Voltage Output Format for Stratix® 10 Devices with the –V Power Option table, and the Supported Commands for the PMBus Master Mode table for the voltage regulator requirements details.

Other
Device address in PMBus Slave mode 17 7-bit hexadecimal value Device address in the PMBus Slave mode.
Slave device_0 address 16 7-bit hexadecimal value

External power regulator address.

This parameter must be non-zero when you are using the PMBus Master mode.
Slave device_1 address 16 7-bit hexadecimal value External power regulator address.
Slave device_2 address 16 7-bit hexadecimal value External power regulator address.
Slave device_3 address 16 7-bit hexadecimal value External power regulator address.
Slave device_4 address 16 7-bit hexadecimal value External power regulator address.
Slave device_5 address 16 7-bit hexadecimal value External power regulator address.
Slave device_6 address 16 7-bit hexadecimal value External power regulator address.
Slave device_7 address 16 7-bit hexadecimal value External power regulator address.
Voltage output format 16 Auto discovery

The voltage output format when the operation mode is PMBus Master.

If the voltage output format is the Auto discovery or Direct format, you must set the following parameters:

  • Direct format coefficient m
  • Direct format coefficient b
  • Direct format coefficient R

If the voltage regulator is the Linear format, you must set the Linear format N parameter. 18

For all voltage output format, you must also select the correct "translated voltage output unit".
Direct format
Linear format
Direct format coefficient m 16 Signed integer: -32768 to 32767 Direct format coefficient m of the slave device type when the operation mode is PMBus Master.
Direct format coefficient b 16 Signed integer: -32768 to 32767 Direct format coefficient b of the slave device type when the operation mode is PMBus Master.
Direct format coefficient R 16 Signed integer: -128 to 127 Direct format coefficient R of the slave device type when the operation mode is PMBus Master.
Linear format N 16 –16 to 15 Output voltage command when the voltage output format is set to the Linear format.
Translated voltage value unit 16 millivolts Indicates the translated output voltage is in millivolts (mV) or volts (V).
volts
Enable PAGE command 16 Enable By enabling the PAGE command, the FPGA PMBus Master uses the PAGE command to set all the output channels (0xFF) on registered regulator modules to respond to VOUT_COMMAND. If only specified output channels on registered regulator modules must respond to VOUT_COMMAND, enter the corresponding page value (0x00 – 0xFF).
