Construction of temporal logic contracts for distributed systems, starting from GR(1) specifications. This implementation is experimental, so expect changes.

The dependencies are listed in the file requirements.txt. Installing a suitable version of the package dd can be done as follows.

pip uninstall --yes dd
pip install cython
pip download --no-dependencies dd==0.5.1
tar xzf dd-*.tar.gz
cd dd-*/
export CUDD_VERSION=3.0.0
export CUDD_GZ=cudd-${CUDD_VERSION}.tar.gz
curl -sSL https://sourceforge.net/projects/cudd-mirror/files/${CUDD_GZ}/download > ${CUDD_GZ}
tar -xzf ${CUDD_GZ}
python -c 'from download import make_cudd; make_cudd()'
python setup.py install --cudd

These steps will download and build the C library CUDD, and then build and install dd, including the Cython module dd.cudd. The steps are based on this .travis.yml. The repository contract_maker requires dd==0.5.1 (as listed in the file requirements.txt), and the above steps correspond to that version of dd.
