User-Defined DIP Switch
Board reference SW4 is a 8-pin DIP switch. The switches are user-defined, and are
provided for additional FPGA input control. There is no board-specific function for
these switches.
Table 2–25 lists the user-defined DIP switch schematic signal names and their
corresponding Stratix V GX pin numbers.
Table 2–26 lists the user-defined DIP switch component reference and the
manufacturing information.
User-Defined LEDs
The development board includes eight user-defined LEDs. Board references D18
through D25 are user LEDs which allow status and debugging signals to be driven to
the LEDs from the designs loaded into the Stratix V GX device. The LEDs illuminate
when a logic 0 is driven, and turns off when a logic 1 is driven. There is no
board-specific function for these LEDs.
