1.6.1. HPS Supply Pins
Pin Name | Pin Functions | Pin Description | Connection Guidelines |
---|---|---|---|
VCCL_HPS | Power | VCCL_HPS supplies power to the HPS core. | The VCCL_HPS power supply voltage could vary from 0.8 V to 0.94 V for –1V, –2V, or –3V devices with the SmartVID feature depending on the SmartVID setting in the device. When using –2L or –3X devices, you must connect to either 0.9 V or 0.94 V supply. If you are using 0.9 V supply, VCCL_HPS can be connected to VCCERAM. VCCL_HPS can be shared with VCC and VCCP if they are at the same voltage level only when using –1V, –2V, or –3V devices (with the SmartVID feature). VCCL_HPS cannot be shared with VCC and VCCP when using –2L or –3X devices. VCCL_HPS always needs to be equal to VCCPLLDIG_HPS. Use the Stratix® 10 Early Power Estimator (EPE) or Power Thermal Calculator (PTC), and the Quartus® Prime Power Analyzer to determine the current requirements for VCCL_HPS and other power supplies. Decoupling for these pins depends on the design decoupling requirements of the specific board. See Notes 2, 3, 4, and 6 in Notes to Stratix® 10 HPS Pins. If you do not intend to utilize the HPS in the Stratix® 10 SX device, you must still provide power to the HPS power supply. Do not leave VCCL_HPS floating or connected to GND. |
VCCIO_HPS | Power | The HPS dedicated I/Os support 1.8V voltage level. | Connect these pins to 1.8 V power supply. If these pins have the same voltage requirement as VCCIO and VCCIO_SDM, you have the option to source the VCCIO_HPS pins from the same regulator as VCCIO and VCCIO_SDM. Decoupling for these pins depends on the design decoupling requirements of the specific board. See Notes 2, 3, 4, and 8 in Notes to Stratix® 10 HPS Pins. If you do not intend to utilize the HPS in the Stratix® 10 SX device, you must still provide power to the HPS power supply. Do not leave 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 low noise power supply through a proper isolation filter. You have the option to share VCCPLL_HPS with the same regulator as VCCPT when all power rails require 1.8 V but only with a proper isolation filter. Decoupling for these pins depends on the design decoupling requirements of the specific board. See Notes 2, 3, 4, and 7 in Notes to Stratix® 10 HPS Pins. If you do not intend to utilize the HPS in the Stratix® 10 SX device, you must still provide power to the HPS power supply. Do not leave 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. For more information about isolation filters, refer to AN 583: Designing Power Isolation Filters with Ferrite Beads for Altera® FPGAs . If you do not intend to utilize the HPS in the Stratix® 10 SX device, you must still provide power to the HPS power supply. Do not leave VCCPLLDIG_HPS floating or connected to GND. |
You can use the HPS Component in the Platform Designer to assign the HPS Dedicated I/Os to various HPS Peripherals and one hps_osc_clk input. The handoff files generated by the Platform Designer during the Quartus® Prime compilation will set the pin mux registers (pin0sel through pin47sel) and the HPS Oscillator Clock register (hps_osc_clk) to their respective HPS pin functions.
For more information about the valid combinations of the HPS I/O assignments, refer to the Hard Processor System Pin Information for Stratix® 10 Devices .
