Note that the software tree (sw/) is separate from the gateware tree (gw/) and the build trees (build/) are separate from the sw and gw source trees.

The build trees are CMake build trees generated by the boxlambda_setup.sh script. The script generates four build trees:

• sim-a7-35: Arty-A7-35T simulation build tree.
• sim-a7-100: Arty-A7-100T simulation build tree.
• arty-a7-35: Arty-A7-35T FPGA build tree.
• arty-a7-100: Arty-A7-100T FPGA build tree.

The build trees are not under version control.
