Due to the nonuniform interconnect scaling in the Deep Sub Micron (DSM) region, the coupling capacitance between wires becomes an increasingly dominant fraction of the total wire capacitance. This couple capacitance introduces server crosstalk which causes delay variations on signal lines and raises signal integrity problems. Therefore, including crosstalk in the timing analysis methods has become imperative for current technologies. And to correctly model the crosstalk, output loading effects, waveform shape and gate driving capability have to be considered. However, most existing crosstalk models have not yet included these factors and consequently suffer from the low accuracy problem. In this article, we propose a noniterative equivalent waveform model that addresses the above mentioned issues. Our experimental results have shown that the new model achieves 3 times speed up and 95% accuracy compared to the existing models. . 2008.

Noise glitches can cause functional errors or failures if they are latched into sequential cells. Thus it is very important to determine or characterize noise failure criteria of sequential cells. However, characterizing noise failure criteria of sequential cells is very computationally expensive because it often requires multiple transient simulations with different clock waveform shapes and alignments, known as clock sweeping. In this paper, we propose a new technique that eliminates the clock sweeping by using the metastable point of sequential cells. Our experiments with industrial circuits have shown that the proposed method is on average 58X faster than the conventional clock sweeping method and its average error is only 2.4%.

Lexical features are influenced by different languages and genres. The study of lexical features in different genres of texts on the same topic is helpful to understand the universalities and peculiarities of languages. This study constructs a research on the lexical feature and word collocations of two self-build corpora (China's economic Legal Policy Corpus and English News Corpus during the COVID-19 pandemic), the methods of Quantitative Linguistics and context interpretation are adopted. It was found that: (1) the word length, word frequency, word cluster and high frequency word distribution in English economic news and Chinese economic legal policies are influenced by language and genre to some extent, and they conform to different functional image distribution; (2) during the COVID-19 pandemic, “development” has been the focus of China's economic legal policies and English news, the two have attached importance to economic recovery and taken a positive attitude toward it in different ways. These findings suggest that: (1) There are some universalities and peculiarities between English economic news and Chinese economic legal policies in the distribution of lexical feature; (2) there is a certain synchronization between laws and news, and both of them maintain a positive and objective attitude toward the economic development during the pandemic. This study carries out a macroscopic investigation on internal structure and external interpretation, which enriches the study on lexical features and cultural features of language and provides some references for relevant studies.
