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

id="<string>"

The unique index of the region, which can be found in the Fabric Key (.xml)

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

name="<string>"

The block name represents the instance name which you can find in the fabric netlists

number_of_bits="<string>"

The total number of configuration bits in this block
