Tile Organization (.xml)
|
||
|
|
------------------------
|
||
|
|
|
||
|
|
The XML-based description language is used to describe how each tile is composed.
|
||
|
|
For example, what programmable blocks, connection blocks and switch blocks should be included.
|
||
|
|
|
||
|
|
Using the description language, users can customize the tiles of an FPGA fabric, as detailed as each component in each tile.
|
||
|
|
|
||
|
|
Under the root node ``<tiles>``, the detailes of tile organization can be described.
|
||
|

.. code-block:: xml
|
||
|
|
|

|
|
<tiles style="<string>"/>
|
||
|
|
</tiles>

Syntax

``````
|
||
|
|
|
||
|
|
Detailed syntax are presented as follows.
|
||
|
|
|
||
|
|
.. option:: style="<string>"
|
||
|
|
|
||
|
|
Specify the style of tile organization. Can be [``top_left`` | ``top_right`` | ``bottom_left`` | ``bottom_right`` | ``custom``]
|
||
|
|
|
||
|
|
.. warning:: Currently, only ``top_left`` is supported!
|
||
|
|
|
||
|
|
The ``top_left`` is a shortcut to define the organization for all the tiles. :numref:`fig_tile_style_top_left` shows an example of tiles in the top-left sytle, where the programmable block locates in the top-left corner of all the tiles, surrounded by two connection blocks and one switch blocks.
