Reference Manual

User-Defined DIP Switch

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

provides additional FPGA or HPS 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 2–12 lists the user-defined DIP switch schematic signal names and their

corresponding Arria V SoC pin numbers.

User-Defined LEDs

Board references D1–D8 are eight user-defined LEDs. The status and debugging

signals are driven to the LEDs from the FPGA or HPS designs loaded into the

Arria V SoC. 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.

Table 2–13 lists the general LED schematic signal names and their corresponding

Arria V SoC pin numbers.
