Abstract

This paper proposes a comprehensive model for testplanning in a core-based environment. The main contributionof this work is the use of several types of TAMs and theconsideration of different optimization factors (area, pinsand test time) during the global TAM and test schedule definition.This expansion of concerns makes possible an efficientyet fine-grained search in the huge design space ofa reuse-based environment. Experimental results clearlyshow the variety of trade-offs that can be explored usingthe proposed model, and its effectiveness on optimizing thesystem test design.
