Reference Manual

General User Input/Output

This section describes the user I/O interface to the FPGA, including the push buttons,

DIP switches, status LEDs, character LCD, and SDI video output/input port.

User-Defined Push Buttons

The development board includes three user-defined push buttons for each FPGA

device. For information on the system and safe reset push buttons, refer to “Setup

Elements” on page 2–21.

Board references S5, S6, and S7 are push buttons that allow you to interact with the

Arria V GX FPGA 1 while S9, S10, and S11 are for use with the Arria V GX FPGA 2.

When you press and hold down the button, the device pin is set to logic 0; when you

release the button, the device pin is set to logic 1. There are no board-specific functions

for these general user push buttons.

Table 2–25 lists the user-defined push button schematic signal names and their

corresponding Arria V GX FPGA device pin numbers.
