Hmm your dynamic power is about 5.6mW per router, while static power is
52mW per router.
The dynamic is probably low because of low utilization, or because the
simulation continued for many cycles even after all 200K packets were
delivered.
The static power definitely seems too high.
Try to look at the breakdown and see if some component seems like an
outlier.
One a side node, I don't think Orion's leakage power models are very
accurate because they just use hard coded numbers and extrapolate them
across technologies.
This is a more recent tool which is more accurate:

You could compute event counts and pass them to DSENT.

Hello,
Thank you for your reply. I have a question on the static and dynamic
power consumed.
I have a simulated a 8 core 8 router mesh NoC with synthetic traffic
where each core injects 200,000 packets in to the network. I have
simulated at 65 nm technology.
The power numbers look like this.
Dynamic Router Power (from ruby.stats) : 0.0459157 W
Static Router Power (from ruby.stats) : 0.420089 W
I am confused as to why is the static power so high compared to the
dynamic power. Shouldn't it be the other way around where the dynamic
power consumed is higher than the static power?
Thanks for your time.
Thanks,
Pavan

That is the combined power for entire NoC.
If you want individual router power, and/or breakdown of
individual components, look at network/orion/NetworkPower.cc

L2 caches on a mesh topology with garnet's fixed pipeline

ruby.stats file that contains router power statistics like router
dynamic power, router static power, router clock power, and total
router power.
