# ClassNameCollision
#-----------------------------------------------------------------------
# A model's class_name is generated during elaboration based on a hash of
# the list of arguments and their values. If two models have the same
# class name, same args, and same arg values (e.g., two Mux's each with 2
# ports and 47 bits, but one is one-hot and one is not), the hashes will
# collide. In Verilog translation, collided names result in both modules
# pointing at the same module definition, so one is incorrect.
#
# This collision is prevented by adding the model's __module__ to the hash
# generation (_gen_class_name). A class's __module__ will be different
# when importing from different modules.
#
# This test case creates two models of class name ClassNameCollisionModel,
# one in this module and one in the Model_dummy_test.py module. They have
# the same name and same args. The test case checks that their Model
# class_name's do not collide after elaborate.

# ClassNameCollisionSameModule
#-----------------------------------------------------------------------
# The ClassNameCollision test case checks for class name collisions due to
# same-name same-args classes in _different_ modules. Collisions can still
# happen if the same-name same-arg classes are in the same module. This
# test case checks for this kind of collision using two classes named
# "ClassNameCollision" placed at different levels of the hierarchy, but
# instantiated with the same name and same args.
#
# TODO: This corner case is not yet fixed and may not need to be fixed. If
# this seems like it is ever going to happen in practice, we will need
# this test case to pass. This test case will pass if we use __class__ in
# the class name generation (_gen_class_name). While this always avoids
# collisions, it also gives a differently named translated Verilog file on
# every run. Having the filename always changing can make it difficult for
# other tools to point to the generated Verilog. Using __module__ in the
# hash generation still avoids class name collisions across modules but
# also keeps the name of the translated Verilog file the same. It means we
# are not avoiding same-class-name same-args collisions in the same
# module, but this seems kind of rare.
