Hi guys,
As pointed out, the physmem in Ruby is "dangling" and only used to functionally
have something to compare with. With recent changes in Ruby I think it can more
or less be removed.
Hopefully we can eventually reach a point where Ruby uses the normal gem5 ports
on the edges and that way we could use the normal DRAM controller both with
classic and Ruby.

Hi Tejasi,
To my knowledge, SimpleDRAM and SimpleMemory cannot work with Ruby directly.
please use the classic memory instead.

Hi All,
I am trying to run se.py using SimpleDDR3 in place of SimpleMemory and I am
getting the error-
fatal: SimpleDRAM system.physmem is unconnected!
The command I am running is:
./build/ALPHA_MESI_CMP_directory/gem5.opt configs/example/se.py -n 16
--cpu-type=timing --clock=1GHz --topology=MeshDirCorners --l2cache
--num-l2caches=16 --l1d_size=32kB --l1i_size=32kB --l2_size=8MB --l1d_assoc=4
--l1i_assoc=4 --l2_assoc=16 --num-dirs=4 --mesh-rows=4 --ruby
--garnet-network=fixed --cmd=splash2/codes/kernels/lu/non_contiguous_blocks/LU
-I 3000000
Could anyone please let me know if I am missing something here?
