4.9.5. Power Fast Discharging
The Intel® Stratix® 10 MX FPGA development kit implements a Fast Discharging circuit to facilitate a rapid discharging the capacitors of certain power rails during system power down sequence. This is to ensure the voltages are at minimum levels in case the system needs to be powered up again. The design is implemented using a Field Effect Transistor (FET), which is turned on to discharge of its respective power rail to ground through a Bleeding resistor during system power down.
The following rails are implemented with Fast Discharging:
- 1p2V_DDR4
- 1p2V_VCCIO_UIB
- HiLo_VDD
- HiLo_VDDQ
- 3p3V
- 2p5V
- VCCM
- 1p8V
- S10_VCCRL_GXB
- S10_VCCRR_GXB
- S10_VCCT_GXB
- S10_VCCERAM
