Seven-Segment Displays

One seven-segment display per FPGA (for a total of three) is available for use. The red Stanley-Electric NAR131SB displays are active Low, using seven inputs to display a character or number plus another input for a decimal point.

Light Emitting Diodes (LEDs)

Each FPGA is able to control four active-high green LEDs. The green is used to distinguish the User LEDs from the blue system LEDs on the Virtex-5 FPGA ML561 Development Board.

Pushbuttons

The ML561 board contains two momentary pushbuttons. Their functions and locations are described in Table 3-14.

Table 3-14:User Pushbuttons

Button	Description	Pin Connection

SW7	PROG_B: Configure FPGA	System ACE Controller: Pin 33

SW4	RESET_N: Reset the FPGA designs	FPGA #1: AH14
		FPGA #2: AH14
		FPGA #3: AH14

The Reset signal goes to a buffer (U32) that provides a separate copy of Reset to each

FPGA.
