Stratix IV GX FPGA Development Board, 530 Edition Reference Manual November 2010 Altera Corporation

Table 2–26 lists the user-defined DIP switch component reference and the

manufacturing information.

User-Defined LEDs

The development board includes general and HSMC user-defined LEDs. This section

describes all user-defined LEDs. For information on board specific or status LEDs,

refer to“Status Elements” on page 2–16.

General User-Defined LEDs

Board references D6 through D13 and D16 through D23 are 16 user LEDs which allow

status and debugging signals to be driven to the LEDs from the designs loaded into

the Stratix IV 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.

Table 2–27 lists the user-defined LED schematic signal names and their corresponding

Stratix IV GX pin numbers.
