Multiview modeling and power intent in Systems-on-chip

Participants : Carlos Gomez Cardenas, Ameni Khecharem, Emilien Kofman, Frédéric Mallet, Julien Deantoni, Robert de Simone.

Power models for embedded architectures (where power consumption is highly constrained) provide an ideal example of a non-functional modeling framework with strong interactions with the functional and performance models: more speed in computation comes at the cost of larger energy consumption. There was also a demand for a framework allowing combinaison of models, each representing a distinct view of the system. We demonstrated as part of the HeLP ANR project 8.2.1.1 , followed by the newly started HOPE ANR project 8.2.1.2 , how such multiview modeling could be done, and how it could be connected down to more concrete simulation code or model, as in SystemC, Docea Power AcePlorer, or Scilab code. The multiview modeling applied to power intent and power managers was described in [35] , and led to the PhD defense of Carlos Gomez Cardenas in December 2013 [16] .
