A Framework Introducing Model Reversibility in SoC Design Space Exploration

摘要

In this paper we present a general framework for the support of flexible models representation and execution in the context of SoC design space exploration. Coming as a C++ library, it allows the user to gather models from its own and existing models into larger and more complete models. Compared to existing modeling systems we introduce the notion of model reversibility that allows the user to turn any parameter appearing in a model into the output : it increases the model flexibility ana enables its reuse in very different problems. Aside from providing specification and execution support, the framework also permits dynamic model sensitivity analysis and efficient parameter sensitivity analysis for closed-formed models. Through this paper we explain our original 3-level hierarchical representation of model and explain meanwhile how it offers flexibility and model robustness using a XML schema grammar.
