In this paper, we propose an automated technique to identify the reasons for un-testable faults and, an interactive Low Coverage Analysis flow to expedite the coverage analysis step, in scan ATPG. We seamlessly use an implication graph to keep track of the reasons that are responsible for each conflict encountered during ATPG. As ATPG progresses, for each fault, all the reasons arising from ATPG constraints...
Peer-to-peer (P2P) systems provide a scalable way to stream content to multiple receivers over the Internet and has become a major type of application traffic. The maximum rate achievable by all receivers is the capacity of a P2P streaming session. We provide a taxonomy of the problem formulations. In each formulation, computing P2P streaming capacity requires the computation of an optimal set of...
In this paper, we propose a new search technique for ATPG, called CONCAT [1], which (a) is based on AND/OR reasoning, (b) integrates conflict driven learning, and (c) avoids over specification of test vectors. The technique works seamlessly (i) between Boolean and non-Boolean gates in industrial designs, (ii) across phases in latch-based designs, (iii) between justification and propagation tasks in...
Traditionally, the channelization structure in IEEE 802.11-based wireless LANs has been fixed: Each access point (AP) is assigned one channel and all channels are equally wide. In contrast, it has recently been shown that even on commodity hardware, the channel-width can be adapted dynamically purely in software. Leveraging this capability, we study the use of dynamic-width channels, where every AP...
