Reference Manual

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.
