Stratix V GT Edition Reference Manual

User-Defined DIP Switch

Board reference SW4 is a 8-pin DIP switch. The switches are user-defined, and are

provides additional FPGA input control. When the switch is in the OPEN or ON

position, a logic 1 is selected. When the switch is in the CLOSED or OFF position, a

logic 0 is selected. There is no board-specific function for these switches.

Table 2–24 lists the user-defined DIP switch schematic signal names and their

corresponding Stratix V GT pin numbers.

Table 2–25 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 that allow status and debugging signals to be driven to

the LEDs from the designs loaded into the Stratix V GT 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.

Table 2–26 lists the user-defined LED schematic signal names and their corresponding

Stratix V GT pin numbers.
