NaxRISCVの試行 (コンパイルとシミュレーション)

ちょっといろいろ試行したくて、NaxRISCVを実行してみる。

github.com

# Get the repo
git clone https://github.com/SpinalHDL/SpinalHDL.git --recursive
git clone https://github.com/SpinalHDL/NaxRiscv.git --recursive
cd NaxRiscv
export NAXRISCV=${PWD}
(cd ext/NaxSoftware && ./init.sh)

# Building riscv-isa-sim (spike), used as a golden model during the sim to check the dut behaviour (lock-step)
sudo apt-get install device-tree-compiler
cd $NAXRISCV/ext/riscv-isa-sim
mkdir build
cd build
../configure --prefix=$RISCV --enable-commitlog  --without-boost --without-boost-asio --without-boost-regex
make -j$(nproc)
g++ --shared -L. -Wl,--export-dynamic -L/usr/lib/x86_64-linux-gnu  -Wl,-rpath,/lib  -o package.so spike.o  libspike_main.a  libriscv.a  libdisasm.a  libsoftfloat.a  libfesvr.a  libfdt.a -lpthread -ldl -lboost_regex -lboost_system -lpthread  -lboost_system -lboost_regex

# Install ELFIO, used to load elf file in the sim 
git clone https://github.com/serge1/ELFIO.git
cd ELFIO
sudo cp -R elfio /usr/include

# Install Verilator
sudo apt-get install git make autoconf g++ flex bison
git clone http://git.veripool.org/git/verilator   # Only first time
unsetenv VERILATOR_ROOT  # For csh; ignore error if on bash
unset VERILATOR_ROOT  # For bash
cd verilator
git pull        # Make sure we're up-to-date
git checkout v4.216
autoconf        # Create ./configure script
./configure
make
sudo make install

# Generate NaxRiscv
cd $NAXRISCV
sbt "runMain naxriscv.Gen"

# Install SDL2, allowing the simulation to display a framebuffer
sudo apt-get install libsdl2-2.0-0 libsdl2-dev

# Compile the simulator
cd $NAXRISCV/src/test/cpp/naxriscv
make compile

一応これでDhrystoneのシミュレーションが実行できた。
