PySysC

A Python package to make SystemC usable from Python. It supports composition of a SystemC/TLM model as well as running the simulation. As of version 0.2 it also allows to run Python functions as part of an SC_THREAD.

How to setup the environment

The installation for PySysC is as follows (using bash shell). The process has been tested under CentOS7 and Ubuntu 20.04. Make sure a newer version of gcc is in your path (tested with gcc-6.3.0). Also the SystemC installation has to be reference with the environment variable SYSTEMC_HOME.

If you get an error complaining about missing Python.h, you need to install Python development headers. See the articel under https://blog.ducthinh.net/gcc-no-such-file-python-h.

# create virtual environment
python3 -m venv pysysc-env
# and avtivate it
. pysysc-env/bin/activate
# update pip to mekae sure we have the newest version
python3 -m pip install --upgrade pip
# install wheel package
python3 -m pip install wheel
# install cppyy, C++ std version needs to match the version used when building the SystemC library
STDCXX=11 python3 -m pip install cppyy
# clone of PySysC
git clone https://git.minres.com/SystemC/PySysC.git
# install PySysC, for development PySysC use 'python3 -m pip install -e`
SYSTEMC_HOME=<path to SystemC> python3 -m pip install PySysC

Running the example

To run the example you need to clone and build the PySysC-SC repo. It contains the code and libraries being used in the example. This project uses Conan.io as package manager so it should be installed (see down below). To deactivate conan and use a SystemC installation just comment out the line setup_conan() in CMakeLists.txt and set the environment variable SYSTEMC_HOME.

Run the router_eample.py

# get the PySysC-SC repo
git clone --recursive https://git.minres.com/SystemC/PySysC-SC.git
# build the project libraries as shared libs
cd PySysC-SC
mkdir -p build/Debug
cd build/Debug
cmake -DCMAKE_BUILD_TYPE=Debug -DBUILD_SHARED_LIBS=ON ../..
make -j components
cd ../..
# now we are ready to run the example
python3 router_eample.py

Installing conan separately

To install conan being used during cmake and build the example project without PySysC you need to execute the following steps:

# install conan into our virtual environment pysysc-env
python3 -m pip install conan
# create the default profile
conan profile new default --detect
# add the repo for SystemC packages used in the project
conan remote add minres https://api.bintray.com/conan/minres/conan-repo

TODO

  • pythonize sc_module with iteration protocol (__next__ and StopIteration exception)
  • add support for SC_METHOD
