Build from sources using Docker¶
Prerequisites¶
For this method you only need to install Docker on your machine.
WARNING
The build_openroad.sh will use the host number of CPUs to compile openroad.
Please check your Docker daemon setup to make sure all host CPUs are available. If you are not sure, you can check with the command below. If the output number is different from the number of CPUs from your machine, then is recommended that you restrict the number of CPUs used by the scripts (see instructions below).
docker run <IMAGE> nproc
# <IMAGE> can be any commonly used OS, e.g., 'centos:centos7'
docker run centos:centos7 nproc
You can restrict the number of CPUs with the -t|--threads N argument:
./build_openroad.sh --threads N
Clone and Build¶
git clone --recursive https://github.com/The-OpenROAD-Project/OpenROAD-flow-scripts
cd OpenROAD-flow-scripts
./build_openroad.sh
Verify Installation¶
The binaries are only available from inside the Docker container, thus to start one use:
docker run -it -u $(id -u ${USER}):$(id -g ${USER}) -v $(pwd)/flow/platforms:/OpenROAD-flow-scripts/flow/platforms:ro openroad/flow-scripts
Then, inside docker:
source ./setup_env.sh
yosys -help
openroad -help
cd flow
make
exit
