| 摘 要： | 为了减少SoC芯片的测试数据，提出了一种基于组扩展编码的测试数据压缩方案。该方案采用变长到变长的编码方式对任意长度的0游程和1游程编码，代码字由标记位、前缀和尾部组成。组扩展码将每组的容量扩大了一倍，能有效压缩芯片测试数据量。理论分析和实验结果表明组扩展编码能取得很好的压缩效果，而且能够更好地适应于不同的测试电路。

| Abstract: | A scheme of test data compression based on the Group and Expansion Code (GEC) was presented to reduce compression data of System-on-a-Chip (SoC). It is a variable-to-variable code based on encoding both 0's run and 1's run, and the code word consists of marked bit, prefix and tail. Due to the characteristics of GEC, which lies in its ability to double capacity of every group, it can compress test data efficiently. Theoretical analysis and experimental results show that the proposed scheme can provide a high... |
