This library is a System Verilog and VHDL parser, preprocessor and code generator for Python/C++. It contains:
- ANTLR4 generated VHDL/(System) Verilog parser with full language support.
- Convertors from raw VHDL/SV AST to universal HDL AST (hdlConvertor::hdlAst and it's python equivalent.).
- Convertors from this HDL AST to SV/VHDL/JSON and other formats.
- Compiler focused utils for manipulation with HDL AST.
- HdlAstVisitor, id resolution, sensitivity detection, vhdl <-> verilog type conversion, ...
- IEEE 1076-2008 (VHDL 2008) and all previous standard, (currently without
tool_directive
andPSL
) - [IEEE 1076-2019] WIP
- IEEE 1800-2017 (SystemVerilog 2017) and all previous standards.
Linux: Installing dependencies (Ubuntu 20.10)
# we recommend to use gcc>=9, Visual Studio 2017 or equivalent
sudo apt install build-essential uuid-dev cmake default-jre python3 python3-dev python3-pip libantlr4-runtime-dev antlr4 ninja-build
Installing this library
# note this may be older version than you see in repo
sudo pip3 install hdlConvertor
# or download repository and run
sudo pip3 install --upgrade --force-reinstall --no-cache-dir git+https://github.com/Nic30/hdlConvertorAst.git
sudo pip3 install -r requirements.txt
sudo python3 setup.py install
# if you are using version from git rather uninstall
# old library first if required
# sudo pip3 uninstall hdlConvertor
Installer also supports other options which may be usefull
python setup.py install --prefix /tmp/python_install/ --build-type Debug -- -DANTLR_JAR_LOCATION=/antlr-4.7.1-complete.jar -- VERBOSE=1
You can also install only C++ library/generate .deb package (nothing specific, just normal cmake-based library)
mkdir build && cd build
cmake .. && cmake . --build
cpack # to generate .deb package
Windows:
Take a look at appveyor.yml and doc/windows_installation_and_build.rst. It is required to download antlr4 first and have visual studio or other c++ compiler installed.
The HDL AST (the parsed code) is represented by objects from hdlConvertor.hdlAst
. Parsing and code modification is straightforward, as you can see in following example
