AXI4Fragmenter
--------------
The AXI4Fragmenter is similar to the :ref:`TileLink-Diplomacy-Reference/Widgets:TLFragmenter`, except it can only
break multi-beat AXI4 transactions into single-beat transactions. This
effectively serves as an AXI4 to AXI4-Lite converter. The constructor for this
widget does not take any arguments.
The AXI4Fragmenter is similar to the :ref:`TileLink-Diplomacy-Reference/Widgets:TLFragmenter`.
The AXI4Fragmenter slices all AXI accesses into simple power-of-two sized and aligned transfers
of the largest size supported by the manager. This makes it suitable as a first stage transformation
to apply before an AXI4=>TL bridge. It also makes it suitable for placing after TL=>AXI4 bridge
driving an AXI-lite slave.
