If you have superuser power, you can install MyHDL as follows:

python install

This will install the package in the appropriate site-wide Python package location.

Otherwise, you can install it in a personal directory, e.g. as follows:

python install --home=$HOME

In this case, be sure to add the appropriate install dir to the $PYTHONPATH.

If necessary, consult the distutils documentation in the standard Python library if necessary for more details; or contact me.

You can test the proper installation as follows:

cd myhdl/test/core

To install co-simulation support:

Go to the directory cosimulation/<platform> for your target platform and following the instructions in the README.txt file.
