74 # M5 Python Configuration Utility
76 # The basic idea is to write simple Python programs that build Python
77 # objects corresponding to M5 SimObjects for the desired simulation
78 # configuration. For now, the Python emits a .ini file that can be
79 # parsed by M5. In the future, some tighter integration between M5
80 # and the Python interpreter may allow bypassing the .ini file.
82 # Each SimObject class in M5 is represented by a Python class with the
83 # same name. The Python inheritance tree mirrors the M5 C++ tree
84 # (e.g., SimpleCPU derives from BaseCPU in both cases, and all
85 # SimObjects inherit from a single SimObject base class). To specify
86 # an instance of an M5 SimObject in a configuration, the user simply
87 # instantiates the corresponding Python object. The parameters for
88 # that SimObject are given by assigning to attributes of the Python
89 # object, either using keyword assignment in the constructor or in
90 # separate assignment statements. For example:
92 # cache = BaseCache(size='64KB')
93 # cache.hit_latency = 3
96 # The magic lies in the mapping of the Python attributes for SimObject
97 # classes to the actual SimObject parameter specifications. This
98 # allows parameter validity checking in the Python code. Continuing
99 # the example above, the statements "cache.blurfl=3" or
100 # "cache.assoc='hello'" would both result in runtime errors in Python,
101 # since the BaseCache object has no 'blurfl' parameter and the 'assoc'
102 # parameter requires an integer, respectively. This magic is done
103 # primarily by overriding the special __setattr__ method that controls
104 # assignment to object attributes.
106 # Once a set of Python objects have been instantiated in a hierarchy,
107 # calling 'instantiate(obj)' (where obj is the root of the hierarchy)
108 # will generate a .ini file.
