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.
