Orion
We have incorporated the Orion interconnection network power models inside Gems. It works with the Garnet "fixed pipeline" model. Various performance counters that are required for power calculations are recorded during the simulation. In the end, they are fed to Orion for reporting the interconnection network power. Note that you might have to set the technology parameters as well as other configuration parameters inside the Orion parameter files correctly, if the default parameters are not what you desire.
