In this paper, we investigate three iDDT-based test methodologies, Double Threshold iDDT, Delta iDDT, and Delayed iDDT, and we compare their effectiveness in the detection of defects in very deep sub-micron random logic circuits. The target defects are resistive opens and resistive bridges. We present preliminary simulation results of 49 defects to study the defect sensitivity of each of the th...

In deep-submicron technologies the primary component of delay is shifting from logic gates to the interconnect network. Buses can no longer be considered as a set of independent lines that don’t interact. A more appropriate model would treat the bus as a distributed system, where a transition on a line would affect adjacent lines as well. However, the transitions on the buses can be grouped int...

A complete and accurate method for static timing analysis of deep sub-micron devices in presence of crosstalk is introduced. This scheme provides an eficient plarforrn forfast and accurate static timing verijcution of large scale transistor and cell level netlists, with coupled interconnects and high switching speeds. This paper presents the solution to the crosstalk problem implemented in the ...

Time-resolved transient absorption spectroscopy with sub-9 fs ultrashort laser pulses in the deep-ultraviolet (DUV) region is reported for the first time. Single 8.7 fs DUV pulses with a spectral range of 255-290 nm are generated by a chirped-pulse four-wave mixing technique for use as pump and probe pulses. Electronic excited state and vibrational dynamics are simultaneously observed for an aq...

We derive expectations for signatures in the measured travel times of waves that interact with thermal anomalies and jets. A series of numerical experiments that involve the dynamic linear evolution of an acoustic wave field in a solar-like stratified spherical shell in the presence of fully 3D time-stationary perturbations are performed. The imprints of these interactions are observed as shift...

Over two-thirds of the surface of the earth is covered by oceans, which have an average depth of about 3800 m. As each drop of ocean water contains > 10 cells, the > 10 microbial cells in the ocean represent the largest reservoir of microbes on earth (Whitman et al., 1998). Communities of bacteria, archaea, protists and unicellular fungi account for most of the oceanic biomass and metabolism. M...

Deep neural networks have demonstrated very promising performance on accurate segmentation of challenging organs (e.g., pancreas) in abdominal CT and MRI scans. The current deep learning approaches conduct pancreas segmentation by processing sequences of 2D image slices independently through deep, dense per-pixel masking for each image, without explicitly enforcing spatial consistency constrain...

Burn-in faces significant challenges in recent CMOS technologies. The self-generated heat of each IC in a burn-in environment contributes to larger currents that can lead to further increase in junction temperatures, possible thermal run away, and yield-loss of good parts. Calculations show that the junction temperature is increasing by 1.45X/generation. This paper estimates the increase in jun...

This paper discusses propagation delay error, transient response, and power consumption distribution due to inductive effects in optimal buffered on-chip interconnects. Inductive effect is said to be important to consider in deep submicron (DSM) VLSI design. However, study shows that the effect decreases and can be neglected in next technology nodes for such conditions. key words: on-chip inter...

Several regular circuit structures are proposed. They provide alternatives to the widely used standard-cell structure and have better predictability and a simpler design methodology. A regular global routing scheme is developed. A design flow for use with of all these regular fabrics is discussed.
