Power and Power-On Sequence

Power Consumption

The maximum power consumption of a module mainly depends on the design which is running on the FPGA.

Xilinx provide a power estimator excel sheets to calculate power consumption. It's also possible to evaluate the power consumption of the developed design with Vivado. See also Trenz Electronic Wiki FAQ.

Power Distribution Dependencies

All on-board voltages of the TEBF0808 are generated out of the extern applied 12V power supply.

There are following dependencies how the initial 12V power supply is distributed to the on-board DC-DC converters, which power up further DCDC converters and the particular on-board voltages:

Image Added

 Figure 12: Power Distribution Diagram

Power-On Sequence Diagram

The power-on sequence of the on-board DC-DC converters depens on the current firmware of the System Controller CPLD U39.

Following diagram visualizes the connection of the DC-DC converter control signals ('Enable', 'Power-Good') with System Controller CPLD U39, which enables the particular on-board voltages.

Image Added

Figure 13: Power-On Sequence Utilizing DCDC Converter Control Signals

The TEBF0808 carrier board manages both the power-on sequence of the mounted TE0808 / TE0803 SoM and the on-board DC-DC converters via System Controller CPLD U39.

The power-on sequence of the TE0808 / TE0803 SoM is managed by utilizing the SoM's DC-DC converter control signals ('Enable', 'Power-Good'), so the DC-DC converters of the SoM dedicated to the particular Power Domains of the Zynq Ultrascale+ MPSoC will be powerer-up in a specific sequence to meet the recommended criteria to power up the Xilinx Zynq Ultrascale+ MPSoC properly.

Core voltages and main supply voltages of the Zynq Ultrascale+ MPSoC have to reach stable state and the "Power Good"-signals of the SoM have to be asserted before other voltages like bank's I/O voltages (VCCOx) can be powered up.

It is important that all PS and PL I/Os are tri-stated at power-on until the "Power Good"-signals are logically high, meaning that all on-module voltages have become stable and module is properly powered up.

Adjustable PL Bank VCCO Voltage FMC_VADJ

The carrier board VCCO voltage 'FMC_VADJ' supplying the PL IO-banks of the MPSoC is provided by DC-DC converter U8 and selectable by the pins 'FMC_VID0' ... 'FMC_VID2' of the System Controller CPLD U17.

Table 25: Bit patterns for fixed values of the FMC_VADJ voltage

Note: These pins of the DC-DC converter U8 are hard-wired to initialiy fix the voltage to 1.8V (see schematic).

Power and Power-On Sequence

Power Consumption

The maximum power consumption of a module mainly depends on the design which is running on the FPGA.

Xilinx provide a power estimator excel sheets to calculate power consumption. It's also possible to evaluate the power consumption of the developed design with Vivado. See also Trenz Electronic Wiki FAQ.

Power-On Sequence Diagram

The power-on sequence of the on-board DC-DC converters depens on the current firmware of the System Controller CPLD U39.

Following diagram visualizes the connection of the DC-DC converter control signals ('Enable', 'Power-Good') with System Controller CPLD U39, which enables the particular on-board voltages.

Figure 12: Power-On Sequence Utilizing DCDC Converter Control Signals

The TEBF0808 carrier board manages both the power-on sequence of the mounted TE0808 SoM and the on-board DC-DC converters via System Controller CPLD U39.

The power-on sequence of the TE0808 SoM is managed by utilizing the SoM's DC-DC converter control signals ('Enable', 'Power-Good'), so the DC-DC converters of the SoM dedicated to the particular Power Domains of the Zynq Ultrascale+ MPSoC will be powerer-up in a specific sequence to meet the recommended criteria to power up the Xilinx Zynq Ultrascale+ MPSoC properly.

Core voltages and main supply voltages of the Zynq Ultrascale+ MPSoC have to reach stable state and the "Power Good"-signals of the SoM have to be asserted before other voltages like bank's I/O voltages (VCCOx) can be powered up.

It is important that all PS and PL I/Os are tri-stated at power-on until the "Power Good"-signals are logically high, meaning that all on-module voltages have become stable and module is properly powered up.

Adjustable PL Bank VCCO Voltage FMC_VADJ

The carrier board VCCO voltage 'FMC_VADJ' supplying the PL IO-banks of the MPSoC (bank 64, 65, 66, 48) is provided by DC-DC converter U8 and selectable by the pins 'FMC_VID0' ... 'FMC_VID2' of the System Controller CPLD U17.

...

FMC_VADJ Value

...

Table 3: Bit patterns for fixed values of the FMC_VADJ voltage

Note: These pins of the DC-DC converter U8 are hard-wired to initialiy fix the voltage to 1.8V (see schematic).

Power Distribution Dependencies

All on-board voltages of the TEBF0808 are generated out of the extern applied 12V power supply.

There are following dependencies how the initial 12V power supply is distributed to the on-board DC-DC converters, which power up further DCDC converters and the particular on-board voltages:
