This paper presents a decompression architecture using a periodically alterable MUX network. Compared to static XORs network, the periodically alterable MUXs network has multiple configurations to decode the input information flexibly. Probability analysis can help us to select the proper parameter when considering the DFT schemes. With the dedicated efforts, the smaller test data volume and test application time can be achieved compared to previous techniques.
