摘要

提出了一种自动测试设备功能测试数据压缩的新方法。提出了一种实用的测试数据二维重排序技术，除测试向量重排序外，还应用了列重排序。提出了一种从二维有序数据中提取原始测试向量的方法。通过对ISCAS基准电路二维有序测试数据的熵优值图验证了该方法的优越性

A Novel Methodology for Functional Test Data Compression

This paper presents a novel approach for compressing functional test data in automatic test equipment (ATE). A practical technique is presented for 2 dimensional (2D) reordering of test data in which additionally to test vector reordering, column reordering is also applied. An ATE based approach to extract the original test vectors from the 2D ordered data is presented. The advantage of the approach is substantiated using the figure of merit of entropy for the 2D ordered test data of ISCAS benchmark circuits
