Re: [Gems-users] Garnet with crossbar topology

[Paul Mejia <pmmejia@xxxxxxxxxxx>]

I want to model a crossbar network with increased network latency as
the size of the crossbar is increased. Any suggestions on how to do
this? I'm thinking of using a single router and changing the number of
pipeline stages to simulate a multi-cycle switch traversal stage.

Thanks,
Paul
