TCL scripts have been generated to rebuild the block design in [[https://www.xilinx.com/products/design-tools/vivado.html|Vivado]], and a ''%%README.txt%%'' file in ''%%proj/%%'' describes how to use them. Additionally, the IO constraints file is provided for the current hardware. | + | All software and firmware is available in [[https://gitlab.com/PalouseRobosub/Electrical/hydro-zynq|the Gitlab repository]].
