LiteX SATA demo
~~~~~~~~~~~~~~~
This example design features a Litex SoC based around VexRiscv soft CPU.
It also includes a DDR controller and a SATA core.
The design targets the `Nexys Video <https://digilent.com/reference/programmable-logic/nexys-video/start>`_ board,
mounting an Artix-7 200T FPGA, and the `FMC adapter board <https://github.com/antmicro/fmc-sata-adapter>`_,
mounting an M.2 SSD.
To build the litex SATA demo example, first re-navigate to the directory that contains examples for Xilinx 7-Series FPGAs.
Then depending on your hardware, run:
.. code-block:: bash
:name: example-litex-sata-nexys-video-group
TARGET="nexys_video" make -C litex_sata_demo
At completion, the bitstreams are located in the build directory:
.. code-block:: bash
litex_sata_demo/build/<board>

.. NOTE::
The generated verilog design file (litesata.v) contains a couple of fixes to properly work with the Yosys+VPR flow.
The fixes are around the GTP high speed transceivers hard blocks.
