±30 mV Switcher 5 Share Source VCC and VCCP from the same regulator, sharing the same voltage plane.
VCCP
VCCERAM 2 0.9 ±30 mV Switcher5 Share

Connect the VCCERAM to a dedicated 0.9 V power supply. You may connect the VCCPLLDIG_SDM power to the VCCERAM power plane with proper isolation filtering.

When implementing a filtered supply topology, you must consider the IR drop across the filter.

VCCPLLDIG_SDM Filter
VCCR_GXB[L,R] 3 1.03 ±30 mV Switcher5 Share

You have the option to source the VCCR_GXB and VCCT_GXB from the same regulator when all the power rails require the same voltage level.

The VCCR_GXB and VCCT_GXB voltage supplies can vary depending on whether it is an L-Tile or H-Tile device as well as the channel configuration (non-bonded versus bonded channels) on each tile. For more information about the voltage requirement for your specific use case, refer to the Stratix® 10 Device Datasheet.

VCCT_GXB[L,R]
VCCPT 4 1.8 ± 5% 6 Switcher5 Share if 1.8 V

You may source VCCPT and VCCIO_SDM from the same regulator. You may connect the VCCIO, VCCIO3V, and VCCBAT to the same power plane if the those power rails are at the same voltage level. You may also connect the VCCH_GXB, VCCA_PLL, VCCPLL_SDM, and VCCADC to the same power plane with proper isolation filtering. Depending on the regulator capabilities, you have the option to share this supply with multiple Stratix® 10 devices.

When implementing a filtered supply topology, you must consider the IR drop across the filter.

VCCIO3D 5 1.8 ± 5%6 Switcher5 Isolate Connect VCCIO3D to a 1.8 V power supply.
VCCFUSEWR_SDM 6 2.4 ±50 mV Switcher5 Isolate Connect VCCFUSEWR_SDM to a dedicated 2.4 V power supply if the SDM fuses need to be written. Leave VCCFUSEWR_SDM unconnected or tie it to VCCPT 1.8 V power if the SDM fuses do not need to be written. Do not tie this pin to GND.
VCCIO3C 7 3.0V/3.3V ±5%6 Switcher5 Isolate

Connect VCCIO3C to a 3.0 V or 3.3 V power supply.

Only 1SG040 (HF35 package), 1SX040 (HF35 package), and 1ST040 (HF35 package) support 3.3 V VCCIO3C.

Each board design requires its own power analysis to determine the required power regulators needed to satisfy the specific board design requirements. An example block diagram using the Stratix® 10 GX device is provided in the following figure.

5 When using a switcher to supply these voltages, the switcher must be a low noise switcher as defined as defined in note 7 of the Notes to Stratix® 10 Core Pins.
6 The supported tolerance for the VCCIO power supply varies depending on the I/O standards. For more details, refer to the I/O standard specification in the Stratix® 10 Device Datasheet. Use the EPE (Early Power Estimator) or Power and Thermal Calculator (PTC), and the Quartus® Prime Power Analyzer tool to assist in determining the power required for your specific design.
