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
provides additional FPGA input control. There is no board-specific function for these
switches.
Table 2–25
lists the user-defined DIP switch schematic signal names and their
corresponding Arria II GX pin numbers.
Table 2–26
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 2–17
.
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.
