Abstract

In this paper, we describe the testmethodology for embedded cores basedsystem-on-a-chip (SoC) which contains amicroprocessor core. First the microprocessorcore is tested for correctness of all theinstructions and then the computation powerof the microprocessor core is used to test theon-chip memories and other cores. A smallIddq test set is also used to detect physicaldefects, the design features to facilitate Iddqtesting are described.
