You should not modify this line.
Board Description Section
The main body of the document is a root element board that has several attributes and
subelements that define the details of the board.
<board Attributes>
<displayname> Text </displayname>
<component Attributes />
...........
<component Attributes />
<configuration Attributes >
<devices> Attributes >
</devices>
<option Attributes >
</option>
</configuration>
</board>
The last line in the file must be a closing tag for the root element board </ board >.
The board attributes have the following definitions:
uniquename= A unique name to reference the board.
family= Device family of the FPGA on board (assuming only one device is on the
board).
The board must contain a displayname subelement containing text that describes the
board. For example:
<displayname>Cyclone II XYZ Board</displayname>
The following component subelements declare the components:
DSP Builder Handbook
Single bit type examples:
<component name="LED0" pin="Pin_E5"/>
<component name="LED1" pin="Pin_B3"/>
where attribute name defines the name of the component on the board and pin
defines the FPGA pin to which the component is connected. The name must match
one of the predefined components and you can use it only once per board.
Fixed-size bus type example:
<component name="DipSwitch" label="S1">
<pin location="Pin_AC13"/> <!-- LSB -->
<pin location="Pin_A19"/>
