1.7.1. HPS Supply Pins

Note: Intel® recommends that you create an Intel® Quartus® Prime design, enter your device I/O assignments, and compile the design. The Intel® Quartus® Prime software will check your pin connections according to I/O assignment and placement rules. The rules differ from one device to another based on device density, package, I/O assignments, voltage assignments, and other factors that are not fully described in this document or the device handbook.

VCCL_HPS Power VCCL_HPS supplies power to the HPS core.

For the range of the VCCL_HPS power supply voltage, refer to the Intel® Agilex™ Device Data Sheet.

Speed Grade Power Supply Voltage (V)
VCCL_HPS/VCC VCCL_HPS
–1 VID

VID or standalone 0.95 (performance boost option)

–2 VID VID (VCCL_HPS)
–3 VID VID (VCCL_HPS)
–4X VID 0.8
–4F 0.8 0.8

VCCL_HPS can be shared with VCC if they are at the same VID voltage level.

If you do not intend to utilize the HPS in the Intel® Agilex™ device, you must still provide power to the HPS power supply. Do not leave the VCCL_HPS floating or connected to GND.

VCCIO_HPS Power The HPS dedicated I/Os support 1.8-V voltage level.

Connect these pins to 1.8-V power supply. You have the option to source VCCIO_HPS pins from the same regulator as VCCIO_SDM.

If you do not intend to utilize the HPS in the Intel® Agilex™ device, you must still provide power to the HPS power supply. Do not leave the VCCIO_HPS floating or connected to GND.

VCCPLL_HPS Power VCCPLL_HPS supplies analog power to the HPS PLLs.

Connect these pins to a 1.8-V power supply. You have the option to share VCCPLL_HPS with the same regulator as VCCPLL_SDM.

If you do not intend to utilize the HPS in the Intel® Agilex™ device, you must still provide power to the HPS power supply. Do not leave the VCCPLL_HPS floating or connected to GND.

VCCPLLDIG_HPS Power Digital power supply of the PLL in HPS.

Connect this to the VCCL_HPS with proper isolation filtering.

If you do not intend to utilize the HPS in the Intel® Agilex™ device, you must still provide power to the HPS power supply. Do not leave the VCCPLLDIG_HPS floating or connected to GND.
