Can you pass reference of a simobject as a parameter to another simobject in the configuration ( config.py ) file? How? For example, I have an independent simobject class like Center_Ctrl and a class Cache. ( Center_Ctrl could not be a variable of the class object Cache but Cache could have reference ( pointer) of center_ctrl to call some demo function and vice versa) Now, I want something like this: center_ ctrl = Center_Ctrl( parameters) cache1 = Cache( parameters) cache2=Cache(parameters) cache1.cctrl = center_ctrl cache2.cctrl = center_ctrl and inside the Cache class, this cctrl variable will have the pointer or reference to the center_ctrl simobject. How could I do that ?

You need to add an attribute to the Cache python SimObject class: > cctrl = Param.Center_Ctrl(“<description>”) You will need to import Center_Ctrl from m5.objects before as well. You can find hundreds of examples of this construct in most python SimObject classes. Regards, Gabriel
