Table 2–24 lists the user-defined DIP switch component reference and manufacturing
information.
User-Defined LEDs
The board includes general and HSMC user-defined LEDs. This section discusses all
user-defined LEDs. For information about board specific or status LEDs, refer to
“Status Elements” on page 2–19 .
General User-Defined LEDs
Board references D20 through D27 are eight user LEDs, which allow status and
debugging signals to be driven to LEDs from the FPGA designs loaded into the
Stratix III device. The LEDs illuminate when a logic 0 is driven, and do not illuminate
when a logic 1 is driven. There is no board-specific function for these LEDs.
Table 2–25 lists the general user LED reference number, schematic signal name, and
corresponding Stratix III device pin number.
