Hi Runjie,
The memory controllers are still instantiated, and are used by the devices I
suspect. It would be great if Ruby could split the directory and the actual
memory controller so we would attached e.g. The SimpleDRAM model to Ruby, but
at the moment that is not possible.

Hi, Andreas
Thanks for your respond. I noticed that if I change --mem-type in the cmd
line, the item [system.mem_ctrls] in config.ini would change accordingly. So
when you say --mem-type does not work with Ruby, what do you mean exactly? Does
system.mem_ctrls get bypassed and system.ruby.dir_cntrl0.directory takes over
in Ruby simulation? If so, why stats.txt still have non-zero stats for
system.mem_ctrls?
Hope my questions make sense.
Thanks!
