Hi Lisa,
As mentioned by you, I have read the webpage. I was
trying something like -
"root = Root(clock = '1THz',
system = makeLinuxAlphaSystem(mem_mode, bm[0]))
root.system.cpu =
[AtomicSimpleCPU(),AtomicSimpleCPU()]
root.system.cpu[0] = cpu
cpu.connectMemPorts(root.system.membus)
cpu.mem = root.system.physmem
root.system.cpu[1] = cpu2
cpu2.connectMemPorts(root.system.membus)
cpu2.mem = root.system.physmem "
in fs.py file. But I am getting the following error -
"Error in unproxying param 'cpu' of system.intrctrl
Traceback (most recent call last):

Any help or suggestion is appreciated.
Thanks in advance.
