Abstract
A lossless compression method for a test vector has following steps: S01: converting the test vector into a data stream with A rows and B columns, the data stream is expressed in binary; S02: compressing the data stream a column by a column sequentially to form compressed words and uncompressed words corresponding to test datum of each of the B columns; a compression method for the test datum of each of the B columns comprises: setting a window with a width of 1 bit and a depth of M rows, and sliding the window down a row by a row from top of test datum of a column, and forming the compressed words and the uncompressed words corresponding to the test datum of each of the B columns; S03: converging the compressed datum of the test datum of each of the B columns to form a compressed data stream.
