Table 2–23 lists the user-defined push-button switch component reference and the

manufacturing information.

User-Defined DIP Switches

Board reference SW2 is a 4-pin DIP switch. The switches in SW2 are user-defined and

provided for additional FPGA input control. There is no board-specific function for

these switches.

Table 2–24 lists the user-defined DIP switch schematic signal names and their

corresponding Arria II GX pin numbers.

Table 2–25 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 D7 through D10 are four user-defined LEDs which allow status and

debugging signals to be driven to the LEDs from the FPGA designs loaded into the

Arria II 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.
