4.6. User Input-Output Components

This section describes the user I/O interface to the FPGA. The following I/O elements are described:
  • User-defined Pushbuttons
  • User-defined DIP Switches
  • User-defined LEDs

User-Defined Pushbuttons

This development kit includes 4 user-defined pushbuttons and 4 system pushbuttons that allow you to interact with the Intel® Stratix® 10 TX FPGA. When you press and hold down the pushbutton, the device pin is set to logic 0; when you release the pushbutton, the device pin is set to logic 1. There is no board-specific function for these general user pushbuttons.

The table below lists the pushbuttons, schematic signal names and their corresponding Intel® Stratix® 10 TX FPGA device pin numbers.

S5 PGM_SEL System Pushbutton N/A
S6 PGM_CONFIG System Pushbutton N/A
S7 MAX_RESETn System Pushbutton N/A
S8 CPU_RESETn System Pushbutton R35

User-Defined DIP Switch

Board reference SW4 and SW5 are two 4-pin DIP switches. The switches are user-defined and provides additional FPGA input control. When the switch is in the OPEN or OFF position, a logic 1 is selected. When the switch is in the CLOSED or ON position, a logic 0 is selected. There is no board-specific function for these switches.

The table below lists the schematic signal names of each DIP switch and their corresponding Intel® Stratix® 10 TX FPGA pin numbers.

SW4.1 S10_UNLOCK K22

User-Defined LEDs

The development board includes 8 user-defined LEDs. Board references D12 through D19 are user LEDs that allow status and debugging signals to be driven to the LEDs from the designs loaded into the Intel® Stratix® 10 TX FPGA 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.

The table below lists the user-defined schematic signal names and their corresponding Intel® Stratix® 10 TX FPGA device pin numbers.
