In ultra-deep submicro technology, two of the paramount reliability concerns are soft errors and device aging. Although intensive studies have been done to face the two challenges, most take them separately so far, th...

Critical path selection is very important in delay testing. Critical paths found by conventional static timing analysis (STA) tools are inadequate to represent the real timing of the circuit, since neither the testabi...

With the increasing demand and the wide application of high performance commodity multi-core processors, both the quantity and scale of data centers grow dramatically and they bring heavy energy consumption. Researchers and engineers have applied much effort to reducing hardware energy consumption, but software is the true consumer of power and another key in making better use of energy. system software is critical to better energy utilization, because it is not only the manager of hardware but also the bridge and platform between applications and hardware. In this paper, we summarize some trends that can affect the efficiency of data centers. Meanwhile, we investigate the causes of software inefficiency. Based on these studies, major technical challenges and corresponding possible solutions to attain green system software in programmability, scalability, efficiency and software architecture are discussed. Finally, some of our research progress on trusted energy efficient system software is briefly introduced.
In DSM and nanometer technology, there will present more and more new fault types, which are difficult to predict and avoid. Applying fault tolerant algorithms to achieve reliable on-chip communication is one of the m...

Recently, selective encoding of scan slices is proposed to compress test data. This encoding technique, unlike many other compression techniques encoding all the bits, only encodes the target-symbol by specifying sing...

In modern multi-core chip architecture, the DRAM system is shared by more and more cores and high bandwidth I/O devices. This trend would make the problem of request contention and un-fairness more serious. Previous r...

A critical concern for post-silicon debug is the need to control the chip at clock cycle level. In a single clock chip, run-stop control can be implemented by gating the clock signal using a stop signal. However, data...
