I do not believe it can .. it has modules for the most expensive components (xbar, buffers, wires, arbiters) etc. If you add your own custom module you will probably need to write RTL for it and do synthesis to estimate the area/power. OR you can look into the DSENT codebase for how it models arbiter area and my guess is any control module would have similar complexity as an arbiter ..

I mean get stats for access to links, buffers etc.. and then use some external tool (DSENT / anything else) to get energy/access and then estimate the total energy.

I want to estimate the power and area of some Network-on-Chip topologies using DSENT. I have followed the instructions in gem5-users given by Dr. Krishna (https://www.mail-archive.com/gem5-users@gem5.org/msg15749.html) for this purpose. First, I simulated a Mesh_XY topology with synthetic traffic using this command: build/NULL/gem5.opt configs/example/garnet_synth_traffic.py --network=garnet --num-cpus=64 --num-dirs=64 --topology=Mesh_XY --mesh-rows=8 --sim-cycles=10000000 --synthetic=uniform_random --precision=3 --injectionrate=0.02 --router-latency=1 --link-latency=1 --link-width-bits=16 --routing-algorithm=0 Then, I built dsent using this command: python ./util/on-chip-network-power-area.py . m5out ext/dsent/configs/router.cfg ext/dsent/configs/electrical-link.cfg After that, it compiles dsent, but it gives this error: ("ERROR: Garnet network not used in '", './m5out/config.ini') To get past this error, I changed line 70 in on-chip-network-power-area.py from <unnamed.png> to <unnamed_2.png> But now I get the following error: Traceback (most recent call last): File "./util/on-chip-network-power-area.py", line 219, in <module> main() File "./util/on-chip-network-power-area.py", line 216, in main buffers_per_control_vc, ni_flit_size_bits) File "./util/on-chip-network-power-area.py", line 161, in parseStats ["grep", pattern, stats_file]), '\n', -1) File "/usr/lib/python2.7/subprocess.py", line 223, in check_output raise CalledProcessError(retcode, cmd, output=output) subprocess.CalledProcessError: Command '['grep', 'sim_seconds', './m5out/stats.txt']' returned non-zero exit status 1 It seems that on-chip-network-power-area.py cannot parse the stats. What causes this error to happen and how can I fix it? Warm regards, Ali
