Two-Step Dynamic Encoding for Linear Decompressors

In this paper, a new linear decompressor is presented. A specific two-step encoding is incorporated in the implication process to exploit the degree of freedom during ATPG. The proposed decompressor achieves on average 247X test application time reduction for 10 industrial cores. A comparison with multiple seeds per pattern shows that the proposed decompressor achieves higher test application time reduction with fewer test patterns for 7 out of 10 industrial cores.
