| Abstract(in English) | Test compression / decompression scheme using Huffman coding is efficient in reducing the test application cost, i.e., the test application time and the size of the storage on an LSI tester. The authors in literature [14] have proposed an architecture of an embedded decompressor with a buffer for this scheme. In this paper, we propose a method for reducing the size of the buffer in the embedded decompressor. Since the buffer size depends on the input order of test vectors, we propose an algorithm for ordering test vectors in order to reduce the size of the buffer. The algorithm is based on fluctuations in buffered data for each test vector. Experimental results show a case where the ordering algorithm can reduce the size of the buffer by 97%. |
