Similar to the interconnection architectures, deadlock occurs in NoC architectures when a group of packets are unable to make progress because they are waiting on one another to release resources. Despite its effectiveness in reducing buffer requirements, wormhole-switching technique is susceptible to deadlock. In wormhole switching, the resources are virtual channel and their corresponding buffers. Here, cyclic dependency on flit buffers occurs among several packets. As a result, the network is clogged with packets without making any progress.
