The main idea of the proposed approach is to analyze the original test data by partition them into blocks. We will fill the don't care bits in each block and see if the block is filled by 1 is better than by 0, the block will be encoded by FDR. If the block is encoded by FDR, the input of the corresponding sub-scan chain will be negate by a not gate. The experimental result shows the proposed approach can outperform than FDR coding.
