Stratix II EP2S180 DSP Development Board Reference Manual
When power is applied to the board and SW9 is in the "ON" position, the
Power-on LED (LED7) illuminates. At that time, the MAX device (U10)
programs the Stratix II device (U18) from one of 4 flash memory spaces
reserved for configuration information. If configuration is successful, the
CONF_DONE LED (LED5) illuminates.

Apply Power
Apply power to the board by connecting the 16-V DC power supply
adapter in the DSP Development Kit, Stratix II Professional Edition to the
on-board power adapter connector (J22), and then switch SW9 to the ON
position. All of the board components draw power either directly from
this 16-V supply or from the 3.3-V, 1.2-V, and 5-V regulators that are
powered by the 16-V supply.

Reconfigure the Stratix II device.
If the Stratix II device is programmed with a design in one of the
user configuration memory spaces or using the JTAG connector
(J21), both the CONF_DONE LED (LED5) and the USER LED
(LED1) illuminate. For more information, refer to
“Configuration Status LEDs” on page
The 3.3-V supply provides V
LVTTL board components. The 1.2-V supply provides V
the Stratix II device.
The Stratix II EP2S180 device, the A/D and D/A converters, and
power regulator U22 become hot as the board is used. Because
their surface temperature may significantly increase, do not
touch these devices while power is applied to the board.
