In this work, the design of Lossless 2-D DWT(Discrete Wavelet Transform) using Lifting Scheme Architecture will be modeled using the Verilog HDL andits functionality were verified using the Modelsim tool and can be synthesized using the Xilinx tool.
Instead of inserting additional logic at the gate level that may introduce additional delay on critical paths, the proposed method modifies the design at the register transfer level (RTL) and uses the synthesis tools to automatically deal with timing analysis and optimization.
Key words: Automatic test pattern generation (ATPG), design for testability (DFT), functional power, power-sensitive scan cell, scan-based test.
