General Guidelines
~~~~~~~~~~~~~~~~~~
2020-03-09 14:58:24 -05:00
OpenFPGA uses CMake to generate the Makefile scripts
In general, please follow the steps to compile
2020-05-25 01:31:01 -05:00
.. code-block :: shell
2020-03-09 14:58:24 -05:00
git clone https://github.com/LNIS-Projects/OpenFPGA.git
cd OpenFPGA
mkdir build
cd build
2020-07-04 20:19:06 -05:00
cmake ..
2020-03-09 14:58:24 -05:00
make
.. note :: OpenFPGA requires gcc/g++ version >5
.. note :: cmake3.12+ is recommended to compile OpenFPGA with GUI
.. note :: recommand to use `` make -j `` to accelerate the compilation
2020-10-05 15:27:08 -05:00
.. note :: VPR's GUI requires gtk-3, and can be enabled with `` cmake .. -DVPR_USE_EZGL=on ``

**Quick Compilation Verification**
2020-03-09 14:58:24 -05:00
To quickly verify the tool is well compiled, user can run the following command from OpenFPGA root repository
2020-05-25 01:31:01 -05:00
.. code-block :: shell
2020-03-09 14:58:24 -05:00
python3 openfpga_flow/scripts/run_fpga_task.py compilation_verification --debug --show_thread_logs
Dependencies

~~~~~~~~~~~~
2020-03-09 14:58:24 -05:00
Full list of dependencies can be found at travis_setup_link_
In particular, OpenFPGA requires specific versions for the following dependencies:
:cmake:
version >3.12 for graphical interface
:iverilog:
version 10.1+ is required to run Verilog-to-Verification flow
.. _travis_setup_link: https://github.com/LNIS-Projects/OpenFPGA/blob/0cfb88a49f152aab0a06f309ff160f222bb51ed7/.travis.yml#L34

If some of these dependencies are not installed on your machine, you can choose to use a Docker (the Docker tool needs to be installed).
For the ease of the customer first experience, a Dockerfile is provided in the OpenFPGA folder. A container ready to use can be created with the following command
2020-05-25 01:31:01 -05:00
.. code-block :: shell
2020-03-09 14:58:24 -05:00
docker run lnis/open_fpga:release
.. note :: This command is for quick testing. If you want to conserve your work, you should certainly use other options, such as `` -v `` .
Otherwise, a container where you can build OpenFPGA yourself can be created with the following commands
2020-05-25 01:31:01 -05:00
.. code-block :: shell
2020-03-09 14:58:24 -05:00
docker build . -t open_fpga
docker run -it --rm -v $PWD:/localfile/OpenFPGA -w="/localfile/OpenFPGA" open_fpga bash
For more information about dock, see dock_download_link_
.. _dock_download_link: https://www.docker.com/products/docker-desktop
To build the tool, go in the OpenFPGA folder and follow the compilation steps
.. note :: Using docker, you cannot use `` make -j `` , errors will happen
