Coverage Packages
=================

All coverage packages should be extended from :any:`_coverage.CoverPackage`.

In the constructor the user must declare the variables to be sampled and create the AVL Coverage Groups, Points and Crosses.

The user can use the global :any:`_isa.ISA` dictionary and :any:`_isa.Encoding` class to declare the bins.

Once delcared an instance of the class must be added to the :any:`_coverage.COVERPACKAGES` list. As this is called later, Extensions can be used to filter.

.. literalinclude:: ../../../avl_riscv_coverage/coverage_packages/_opcodes.py
    :language: python

Adding Coverage
---------------

The user can add --packages to the command line to add directories to the list of included coverage packages

.. code-block:: bash

    avl_riscv_coverage --packages dir1 --packages dir2

All python files in the provided directories will be includes.
