Using the Board
Using the Board 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.

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 2–14 .
To configure the board with a new design, the designer should perform
the following steps, explained in detail in this section.
3. Apply power to the board.
4. Reconfigure the Stratix II device.
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.
1
The 3.3-V supply provides V
CCIO
to the Stratix II device and all
LVTTL board components. The 1.2-V supply provides V
CCINT
to
the Stratix II device.
When power is applied to the board, the Power On LED (LED7)
illuminates.
c 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
.
