5.1.4.1.2. Power Management and VID Parameters
Parameters | Value | Description |
---|---|---|
Bus speed mode 12 | 100 KHz | Bus speed mode of PMBus interface when operating in the PMBus Master mode. |
400 KHz | ||
Slave device type12 | TPS53676 | 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 Agilex™ 5 Devices with –V and –E Power Options, and Table: Supported Commands for the PMBus Master Mode for the voltage regulator requirements details. |

Device address in PMBus Slave mode13 | 7-bit hexadecimal value | Device address in the PMBus Slave mode. |
Number of slave devices | 1 to 7, or All | Indicates the number of voltage regulator in the system. |
PMBus device 0 slave address12 | 7-bit hexadecimal value | External power regulator address. This parameter must be non-zero when you are using the PMBus Master mode. |
PMBus device 1 slave address12 | 7-bit hexadecimal value | External power regulator address. |
PMBus device 2 slave address12 | 7-bit hexadecimal value | External power regulator address. |
PMBus device 3 slave address12 | 7-bit hexadecimal value | External power regulator address. |
PMBus device 4 slave address12 | 7-bit hexadecimal value | External power regulator address. |
PMBus device 5 slave address12 | 7-bit hexadecimal value | External power regulator address. |
PMBus device 6 slave address12 | 7-bit hexadecimal value | External power regulator address. |
PMBus device 7 slave address12 | 7-bit hexadecimal value | External power regulator address. |
Voltage output format12 | Direct format | The voltage output format when the operation mode is PMBus Master. If the voltage output format is the Direct format, you must set the following parameters:
If the voltage regulator is the Linear format, you must set the Linear format N parameter. 14 For more information about the parameters, refer to your selected voltage regulator data sheet. For all voltage output format, you must also select the correct "translated voltage output unit". |
Linear format | ||
Direct format coefficient m12 | Signed integer: -32768 to 32767 | Direct format coefficient m of the slave device type when the operation mode is PMBus Master. For more information about the coefficient value, refer to the respective voltage regulator data sheet. |
Direct format coefficient b12 | Signed integer: -32768 to 32767 | Direct format coefficient b of the slave device type when the operation mode is PMBus Master. For more information about the coefficient value, refer to the respective voltage regulator data sheet. |
Direct format coefficient R12 | Signed integer: -128 to 127 | Direct format coefficient R of the slave device type when the operation mode is PMBus Master. For more information about the coefficient value, refer to the respective voltage regulator data sheet. |
Linear format N12 | Signed integer: –16 to 15 | Output voltage command when the voltage output format is set to the Linear format. |
Translated voltage value unit12 | millivolts | Indicates the translated output voltage is in millivolts (mV) or volts (V). |
volts | ||
Enable PAGE command12 | 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). |
Disable | ||
Enable status_byte for polling | Enable | By enabling the STATUS_BYTE polling in the master mode, the firmware sends the STATUS_BYTE command for every 500 ms. If any errors are found, the STATUS_BYTE pin is asserted. The error message queue (EMQ) provides the full error details. 15 |
Disable | ||
Diagnostic Boot | Enable | The diagnostic boot feature performs additional checks of the configuration and operation of the voltage regulator. This feature adds to the configuration time and should be enabled during the board bring-up operations. |
Disable | ||
Disable VID for debug purpose only | Enable | This option is for debug purpose only. When you enable this option, you must set the device operating voltage to 0.8 V. VID is disabled, and the device performance and functionality are not guaranteed. |
