CUDD is a binary decision diageram (BDD) package that is used to
improve conditional timing arc handling, constant propagation, and
power activity propagation and spice netlist generation.

activity propagation and spice netlist generation.
CUDD is available
[here](https://github.com/davidkebo/cudd/blob/main/cudd_versions/cudd-3.0.0.tar.gz).
When building CUDD you may use the `--prefix ` option to `configure` to
install in a location other than the default (`/usr/local/lib`).
```
cd $HOME/cudd-3.0.0
./configure --prefix $HOME/cudd-3.0.0
make
make install
Unpack and build CUDD.
cd <opensta>/build
cmake -DCUDD_DIR=$HOME/cudd-3.0.0 ,.
```
tar xvfz cudd-3.0.0.tar.gz
cd cudd-3.0.0
./configure
make
```
You can use the "configure --prefix" option and "make install" to install CUDD
in a different directory.
