عنوان انگلیسی Efficient Delay Characterization Method to Obtain the Output Waveform of Logic Gates Considering Glitches
چکیده انگلیسی مقاله Accurate delay calculation of circuit gates is very important in timing analysis of digital circuits. Waveform shapes on the input ports of logic gates should be considered, in the characterization phase of delay calculation, to obtain accurate gate delay values. Glitches and their temporal effect on circuit gate delays should be taken into account for this purpose. However, the explosive number of combinations of waveform shapes, which can be applied to the input ports of logic gates, causes existing lookup-based methods to have huge space requirements. In this article, instead of considering all possible combinations of waveform shapes in the characterization phase of delay calculation process, the least number of combinations, which are dominant in determining the waveform shape of gate output, is presented. Multivariate Polynomial Regression (MPR) method is used to further reduce the required memory space. Exploration of the possible MPR analyses is performed to find the best regression case with proper memory space reduction and precision. Attained results show a 1.013E6 times reduction in storage space required for storing parameters utilized in extraction of output waveform characteristics in comparison to a state of the artwork, accompanied by acceptable precision.
