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.
