User-Defined DIP Switch
Board reference SW3 is a four-pin DIP switch. This switch is user-defined and
provides additional FPGA input control. There are no board-specific functions for this
switch.
Table 2–20 lists the user-defined DIP switch schematic signal names and their
corresponding Arria V GX pin numbers.
Table 2–21 lists the user-defined DIP switch component reference and the
manufacturing information.
User-Defined LEDs
The starter 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 LEDs
Board references D20 through D23 are four user-defined LEDs. The status and
debugging signals are driven to the LEDs from the designs loaded into the
Arria V GX. There are no board-specific functions for these LEDs.
Table 2–22 lists the general LED schematic signal names and their corresponding
Arria V GX pin numbers.
