One of the challenges for asynchronous NoC-based systems design is testing asynchronous network architectures for manufacturing defects. To improve the testability of asynchronous NoCs, we have developed a scalable and configurable asynchronous Design-for-Test (DfT) architecture. In this architecture, each asynchronous network node is surrounded by an asynchronous test wrapper and the network communication channels are reused as a high-speed Test Access Mechanism (TAM). This architecture is designed to test all network elements (routers, communication channels), but it can also be used to test computational resources. In this paper, we introduce how to realize and implement the test wrapper in Quasi Delay Insensitive (QDI) asynchronous logic style. The validation and experimental results are also presented.} }
