SoC multiview (meta)modeling for performance, power, and thermal aspects

Participants : Amani Khecharem, Robert de Simone, Emilien Kofman, Julien Deantoni.

In the framework of the ANR HOPE project we progressed the definition of multiview metamodels for the design of Systems-on-Chip) (SoC systems integrating performance, power and thermal aspects. The main concern was to stress regularity and commonalitbetween those views, each developed on "domains" defined as partitions of the original block diagram (clock domains, voltage domains, floorplans,...), and with finite state machine controlers setting the levels of these domains; links between distinct views are originally provided by laws of physics, but then usually identified with discrete allowed values(such as OPP, Operating Performance Points, providing the available frequency-voltage levels for processor clocks).

The corresponding methodology, named MuArch, was reported as Ameni Khacharem PhD document [16].
