Hi Nilay, Thanks for the clarification. I believe the RubyMemoryController is completely Pareto dominated by the vanilla DRAMCtrl module, but if there is any specific feature/setting missing I would be keen to know.
If possible I would like to make sure we use the same controller as a default for all timing simulations (even if the other one would be maintained as a fallback). We could always make RubyMemoryControl a subclass of DRAMCtrl if Brad really wants it to remain in the code base.
