Adding a Hwacha accelerator is as easy as adding the ``DefaultHwachaConfig`` so that it can setup the Hwacha parameters and add itself to the ``BuildRoCC`` parameter.
An example of adding a Hwacha to all tiles in the system is below.

Assigning Accelerators to Specific Tiles with MultiRoCC
-------------------------------------------------------
Located in ``generators/example/src/main/scala/ConfigMixins.scala`` is a mixin that provides support for adding RoCC accelerators to specific tiles in your SoC.
Located in ``generators/chipyard/src/main/scala/ConfigMixins.scala`` is a mixin that provides support for adding RoCC accelerators to specific tiles in your SoC.
Named ``MultiRoCCKey``, this key allows you to attach RoCC accelerators based on the ``hartId`` of the tile.
For example, using this allows you to create a 8 tile system with a RoCC accelerator on only a subset of the tiles.
An example is shown below with two BOOM cores, and one Rocket tile with a RoCC accelerator (Hwacha) attached.
