Reference Manual

Table 2–14 lists the user-defined push button schematic signal names and their

corresponding Cyclone V GT device pin numbers.

User-Defined DIP Switch

Board reference SW1 is a eight-pin DIP switch. This switch is user-defined and

provides additional FPGA input control. When the switch is in the OFF position, a

logic 1 is selected. When the switch is in the ON position, a logic 0 is selected. There

are no board-specific functions for this switch.

Table 2–15 lists the user-defined DIP switch schematic signal names and their

corresponding Cyclone V GT device pin numbers.

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 2–15.

General LEDs

Board references D8–D11 and D15–D18 are eight user-defined LEDs. The status and

debugging signals are driven to the LEDs from the designs loaded into the

Cyclone V GT device. Driving a logic 0 on the I/O port turns the LED on while

driving a logic 1 turns the LED off. There are no board-specific functions for these

LEDs.
