Dependency
----------

An EDAM description is typically composed from multiple cores that have been combined to a larger project. In some cases it can be useful for Edalize flows or tools to be aware of the relation between these cores so that they can recreate the dependency tree. Each Dependency entry contains a list of other cores on which it has a direct dependency.

Example dict of Dependency entries where ::corescore:0 is the toplevel core which depends on ::servant:1.0.0, ::serving:1.0 and ::verilog-axis:0-r2. Both servant and serving in turn depend on serv:

.. code:: yaml

dependencies:
::corescore:0:
- ::servant:1.0.0
- ::serving:0
- ::verilog-axis:0-r2
::serv:1.0.0-r1: []
::servant:1.0.0:
- ::serv:1.0.0-r1
::serving:0:
- ::serv:1.0.0-r1
::verilog-axis:0-r2: []

vunit_options List of String Extra options for the VUnit test runner
add_libraries List of String A list of framework libraries to add. Allowed values include "array_util", "com", "json4hdl", "osvvm", "random", "verification_components"
vunit_runner String Name of the Python file exporting a ``VUnitRunner`` class (must derive from ``edalize.vunit_hooks.VUnitHooks``) that is used to configure and execute test. This allows very customized test control via VUnit's Python-interfaces.
================ ===================== ===========

In case a more advanced VUnit configuration or execution of the testbench is necessary, the option ``vunit_runner`` can be used to specify the filename of a Python script which can hook into the construction, parametrization, and execution of the test runner.
For this to work, the Python script must export a ``class VUnitRunner(vunit_hooks.VUnitHooks)`` which derives from (and optionally overrides) the behavior of ``vunit_hooks.VUnitHooks``.
