User-Defined LEDs
The development board includes general and user-defined LEDs. This section
describes all user-defined LEDs. For information on board specific or status LEDs,
refer to
“Status Elements” on page 2–19 .
General User-Defined LEDs
Board references D18 through D25 and D26 through D33 are two sets of eight pairs
user-defined LEDs. Each of the Arria V GX FPGA have a set of user-defined LEDs.
The LEDs illuminate when a logic 0 is driven, and turns off when a logic 1 is driven.
There are no board-specific functions for these LEDs.
Table 2–29 lists the user-defined LED schematic signal names and their corresponding
Arria V GX FPGA pin numbers.
