source selection.
• ON selects the local 100 Mhz clock source for PCIe
• OFF selects 100 Mhz clock source from the PCIe edge fingers
(Default)
SW4[2]
—CXL
refclk
source selection.
• ON selects local 100 Mhz clock source for CXL
refclk
• OFF select 100 Mhz clock source from CXL connector (Default)
SW4[1]
—PCIe clock spread spectrum enable.
• ON—Enable 0.5% down-spread
• OFF—Spread spectrum disable (Default)
SW5
OFF
Power switch. Slide to ON position to turn on the board. Default is OFF.
SW6
OFF
Intel MAX 10 JTAG_EN switch.
• ON sets the JTAG pins to function as dual-purpose I/O pins and JTAG
function if the JTAG pin sharing option bit is enabled by the Intel
Quartus Prime software.
• OFF sets the JTAG pins to function as JTAG dedicated pins if the JTAG
pin sharing option bit is enabled by the Intel Quartus Prime software
(Default).
3.2. Applying Power to the Development Board
This development kit is designed to operate in two modes:
As a PCIe Add-In Card
When operating the card as a PCIe system, insert the card into an available PCIe slot
and connect a 2x4 pin PCIe power cable from the system to power connectors at J11
of the board.
Note:
When operating as a PCIe add-in card, the board does not power on unless power is
supplied to J11.
In Bench-Top Mode
In bench-top mode, you must supply the board with the provided power 240 W power
supply connected to the power connector J11. The following describes the operation in
bench-top mode.
This development board ships with its switches preconfigured to support the design
examples in the kit.
If you suspect that your board may not be correctly configured with the default
settings, follow the instructions in the Default Switch and Jumper Settings section.
1. The development board ships with design examples stored in the flash memory
device for Avalon-ST x16. Ensure
SW3[1]
is ON and
SW3[2]
is OFF before
powering up the board.
2. Connect the supplied power supply to an outlet and the DC Power Jack to J11 on
the FPGA board.
3. Power Up the Development Kit
