Setup and installation of Verilator¶
SpinalSim + Verilator is supported on both Linux and Windows platforms.
Don’t forget to add the following in your
fork := true
And you will always need the following imports in your Scala testbench:
import spinal.core._ import spinal.core.sim._
You will also need a recent version of Verilator installed :
sudo apt-get install git make autoconf g++ flex bison # First time prerequisites 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 v4.040 autoconf # Create ./configure script ./configure make -j$(nproc) sudo make install echo "DONE"
In order to get SpinalSim + Verilator working on Windows, you have to do the following:
Via MSYS2 get gcc/g++/verilator (for Verilator you can compile it from the sources)
usr\binof MSYS2 into your windows
Check that the JAVA_HOME environnement variable point to the JDK installation folder (ie :
Then you should be able to run SpinalSim + Verilator from your Scala project without having to use MSYS2 anymore.
From a fresh install of MSYS2 MinGW 64-bit, you will have to run the following commands inside the MSYS2 MinGW 64-bits shell (enter commands one by one):
From the MinGW package manager¶
pacman -Syuu # Close the MSYS2 shell once you're asked to pacman -Syuu pacman -S --needed base-devel mingw-w64-x86_64-toolchain \ git flex\ mingw-w64-x86_64-cmake pacman -U http://repo.msys2.org/mingw/x86_64/mingw-w64-x86_64-verilator-4.032-1-any.pkg.tar.xz # Add C:\msys64\usr\bin;C:\msys64\mingw64\bin to your Windows PATH
pacman -Syuu # Close the MSYS2 shell once you're asked to pacman -Syuu pacman -S --needed base-devel mingw-w64-x86_64-toolchain \ git flex\ mingw-w64-x86_64-cmake git clone http://git.veripool.org/git/verilator unset VERILATOR_ROOT cd verilator git pull git checkout v4.040 autoconf ./configure export CPLUS_INCLUDE_PATH=/usr/include:$CPLUS_INCLUDE_PATH export PATH=/usr/bin/core_perl:$PATH cp /usr/include/FlexLexer.h ./src make -j$(nproc) make install echo "DONE" # Add C:\msys64\usr\bin;C:\msys64\mingw64\bin to your Windows PATH
Be sure that your
PATH environnement variable is pointing to the JDK 1.8 and doesn’t contain a JRE installation.
Adding the MSYS2
bin folders into your windows
PATH could potentialy have some side effects.
This is why it is safer to add them as the last elements of the
PATH to reduce their priority.
