User LEDs
This section describes all user-defined LEDs. For information on board specific or
status LEDs, refer to“Status Elements” on page 2–19.
Board references D39 through D42 and D43 through D49 are 12 user LEDs that 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.
Table 2–19 lists the user-defined LED schematic signal names and their corresponding
Stratix V GX pin numbers.
