Re: [gem5-users] Inquiry on router wakeup in garnet2.0

[Krishna, Tushar]

It’s an event driven simulation. Routers wake up if they receive packets from 
the link.

Greetings to all,
I am new to gem5 and I am trying to develop a hierarchical network on chip 
(noc) topology based on Bai et al 2016.  The noc has a pyramidal structure with 
a based layer of 64 routers each connected to network interface (ni). The 2nd 
layer has 16 routers that acts purely as switches (not connected to any ni). 
The 3rd layer has 4 routers also acting purely as switches.

Debug printout, using RubyNetwork flag, shows that only the based 64 routers 
wokeup.  The remaining routers that are not connected to ni did not wakeup. I 
went through the .hh and .cc of the following files; router, basicrouter, 
consumer, networkinterface and garnetnetwork but could not figure out how to 
wakeup these routers.

Can someone please help me out?

Respectfully Yours
