3.1. Default Settings

The Agilex™ 7 FPGA F-Series (2 × F-Tiles) Development Kit ships with its board switches preconfigured to support the design examples in the kit. If you suspect your board might not be correctly configured with the default settings, follow the instructions in the table below to return to its factory settings before proceeding.

Table 4.  Factory Default Switch Settings
Switch Default Position Function
SW1[1:4] ON/OFF/OFF/OFF

PCIe* PRSNT x1/x4/x8/x16 settings switches. Default = x16.

PRSNT x16 PRSNT x8 PRSNT x4 PRSNT x1
ON OFF OFF OFF
SW2 ON Intel® FPGA Download Cable II JTAG Selection switch. Default ON selects the Micro-USB port on-board blaster for FPGA programming.
SW3[1:4] ON/ON/ON/OFF

Configuration mode selection, BMC JTAG selection, and HPS JTAG Bypass switches.

SW3[1:2]—Configuration mode selection. MSEL0 is pulled high. Default mode is AS x4.

Mode SW3[1] - MSEL1 SW3[2] - MSEL2
JTAG OFF OFF
Avalon® streaming interface x16 ON OFF
AS x4 (Fast) ON ON

SW3[3]—BMC JTAG selection.

  • ON selects the on-board blaster as JTAG master when no external blaster is plugged
  • OFF selects the PCIe* RP as JTAG master when no external blaster is plugged
  • Default JTAG chain selects the FPGA

SW3[4]—HPS JTAG Enable.

  • ON enables the HPS as part of the JTAG chain
  • OFF bypasses the HPS from the JTAG chain
  • The HPS is set to bypass by default
SW4[1:4] OFF/OFF/OFF/OFF

Clock features selection switches.

SW4[4]—SI52204 (U25) PCIe* clock power down.

  • ON powers down the PCIe* clocks
  • OFF powers on the PCIe* clocks (Default)

SW4[3] PCIe* refclk source selection.

  • ON selects 100 MHz clock source from the PCIe* edge fingers
  • OFF selects the local 100 MHz clock source for PCIe* (Default)

SW4[2]—CXL refclk source selection.

  • ON selects 100 MHz clock source from CXL connector
  • OFF selects local 100 MHz clock source for CXL refclk (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

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 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 Quartus® Prime software (default).
