Bitstream Distribution File (.xml)
|
|
----------------------------------
|
|
|
|
The bitstream distribution file aims to show
|
|
|
|
- region-level bitstream distribution
|
|
- The total number of configuration bits under each region
|
|
|
|
- block-level bitstream distribution
|
|
- The total number of configuration bits under each block
|
|
- The number of configuration bits per block
|
|
|
|
An example of the file is shown as follows.
|
|
|
|

Region-Level Bitstream Distribution
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Region-level bitstream distribution is shown under the ``<regions>`` code block
|
|
|
|
.. option:: id="<string>"
|
|
|
|
The unique index of the region, which can be found in the :ref:`file_formats_fabric_key`
|
|
|
|
.. option:: number_of_bits="<string>"
|
|
|
|
The total number of configuration bits in this region
|
|
|
|
Block-Level Bitstream Distribution
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Block-level bitstream distribution is shown under the ``<blocks>`` code block
|
|
|
|
.. option:: name="<string>"
|
|
|
|
The block name represents the instance name which you can find in the fabric netlists
|
|
|
|
.. option:: number_of_bits="<string>"
|
|
|
|
