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.
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 Table: SmartVID Regulator Requirements, Table: Supported Voltage Output Format for Stratix® 10 Devices with the –V Power Option, and Table: Supported Commands for the PMBus Master Mode for the voltage regulator requirements details. |

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:
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). |
