| 摘 要： | 文章提出了一种基于多扫描链相容压缩的距离标记压缩方法,该方法可以有效压缩芯片测试数据量。此方法利用相容压缩和基于差分的编码压缩方法两次压缩测试数据,相比类似的编码测试数据压缩方案,具有压缩测试数据传输协议简单、解压控制过程容易实现的突出特点;对ISCAS-85和ISCAS-89部分标准电路硬故障集的实验结果显示,本文建议的方法在压缩效率以及解压的实现上都明显优于混合码。

| Abstract: | The distance-marking compression method based on compatible compression of multiple scan chains is presented,with which the test data can be compressed efficiently.In the method,the test data are compressed twice by making use of compatible compression and the coding compression strategy based on the difference vector.The proposed method has outstanding advantages over the similar test data compression schemes in that the communication protocol of the compression test data is simple and the decompression control procedure is easy.Experimental results of the hard fault set of part of ISCAS-85 and ISCAS-89 benchmark circuits show that the proposed method obviously outperforms the hybrid coding in the compression ratio and the implementation of decompression. |
