CPU Reset Push Button

Each Arria V GX FPGA has a CPU reset push button,

CPU1_RESETn

(S4) for FPGA 1 and

CPU2_RESETn

(S8) for FPGA 2. Both these push button are inputs to the Arria V GX

FPGA

DEV_CLRn

pin and are open-drain I/Os from the MAX II CPLD System

Controller. The push button is the default reset for both the FPGA and CPLD logic.

The MAX II System Controller also drives these push button during POR.

1 You must enable the

CPU_RESETn

signal within the Quartus II software for this reset

function to work. Otherwise, the

CPU_RESETn

acts as a regular I/O pin. When you

enable the signal in the Quartus II software, and then pull high on the board, every

Table 2–17 lists the CPU reset push button component reference and manufacturing

information.

MAX II Reset Push Button

The MAX II reset push button,

MAX_RESETn

, is an input to the MAX II CPLD System

Controller. This push button is the default reset for the CPLD logic.

Table 2–19 lists the MAX II reset push button component reference and manufacturing

information.
