문헌의 현재 NoC 테스트 스케줄링 방법론은 전용 경로 접근 방식을 기반으로 합니다. NoC 라우터와 상호 연결을 통한 물리적 경로는 전체 코어 테스트 기간 동안 외부 테스터에서 단일 코어로 테스트 데이터를 전송하기 위해 할당됩니다. 물리적 채널 대역폭은 일반적으로 테스트 대상 코어의 스캔 속도보다 크기 때문에 이 접근 방식은 내장된 코어의 테스트 동시성을 불필요하게 제한합니다. 우리는 물리적 채널 대역폭을 여러 개의 작은 가상 채널 대역폭으로 나누는 대역폭 공유 접근 방식을 제안합니다. 테스트 일정은 두 개의 보완적인 NoC 래퍼를 사용하여 래퍼 영역 비용과 결과적인 테스트 적용 시간을 공동 최적화한다는 목표 하에 수행됩니다. 실험 결과에 따르면 테스트 적용 시간을 저하시키지 않으면서 영역 오버헤드를 어느 정도 최적화할 수 있는 것으로 나타났습니다. 전용 경로를 기반으로 하는 다른 NoC 스케줄링 접근 방식과 비교하여 당사의 대역폭 공유 접근 방식은 테스트 적용 시간을 최대 75.4%까지 줄일 수 있습니다.

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%.
