Les méthodologies actuelles de planification des tests NoC dans la littérature sont basées sur une approche de chemin dédié ; un chemin physique à travers les routeurs et interconnexions NoC est alloué pour le transport des données de test d'un testeur externe vers un seul cœur pendant toute la durée du test principal. Cette approche limite inutilement la simultanéité des tests des cœurs intégrés, car la bande passante d'un canal physique est généralement supérieure à la vitesse de balayage de n'importe quel cœur testé. Nous proposons une approche de partage de bande passante qui divise la bande passante du canal physique en plusieurs bandes passantes de canal virtuel plus petites. La planification des tests est effectuée dans le but de co-optimiser le coût de la zone d'emballage et le temps d'application des tests qui en résulte à l'aide de deux wrappers NoC complémentaires. Les résultats expérimentaux ont montré que la surcharge de zone peut être optimisée (dans une certaine mesure) sans compromettre le temps d'application du test. Par rapport à d'autres approches de planification NoC basées sur des chemins dédiés, notre approche de partage de bande passante peut réduire le temps d'application des tests jusqu'à 75.4 %.

Abstract: Current NoC test scheduling methodologies in the literature are based on a dedicated path approach; a physical path through the NoC routers and interconnects are allocated for the transportation of test data from an external tester to a single core during the whole duration of the core test. This approach unnecessarily limits test concurrency of the embedded cores because a physical channel bandwidth is typically larger than the scan rate of any core-under-test. We are proposing a bandwidth sharing approach that divides the physical channel bandwidth into multiple smaller virtual channel bandwidths. The test scheduling is performed under the objective of co-optimizing the wrapper area cost and the resulting test application time using two complementary NoC wrappers. Experimental results showed that the area overhead can be optimized (to an extent) without compromising the test application time. Compared to other NoC scheduling approaches based on dedicated paths, our bandwidth sharing approach can reduce the test application time by up to 75.4%.
