A simplified method for characterization of standard library cells based on the linear delay model is presented in this paper. The linear model is chosen as it allows rapid characterization with a modest number of simulations, while achieving acceptable accuracy. All the parameters of cell delays are defined as 50%-to-50% delays, as distinguished from 50%-to-threshold or threshold-to-50% often ...

A small-biased distribution of bit sequences is defined as one withstanding GF (2)-linear tests for randomness, which are linear combinations of the bits themselves. We consider linear combinations over larger fields, specifically, GF (2) for n that divides the length of the bit sequence. Indeed, this means that we partition the bits to blocks of length n and treat each block as the representat...
