Construction and Analysis of Augmented Time Compactors
In this paper, a procedure for constructing time compactors based on a new 3-dimensional augmented product code is presented. Accordingly, augmented time compactors are constructed by assigning a unique triplet   to each scan chain and calculating at least four sets of parity check bits. Parity check bits of each set are XORed into stages of one or more multi-input shift registers. The proposed method allows constructing different classes of time compactors directly based on the coding theory. The constructed augmented time compactors outperform the most advanced time compactors of each respective class. All constructed compactor schemes are strictly defined and establish a clear baseline for future development in this area.
